E XA M Q U EST I O N S
Q1 QUESTION 1 OF 89
A nurse is reviewing discharge instructions with a client diagnosed with asthma who has been prescribed inhaled bronchodilators. Which of the following client
statements indicates an understanding of the priority teaching points for managing their condition at home? (Select all that apply.)
A) "I need to make sure I can use my inhaler correctly to get the full dose of medication."
B) "I should check my pulse oximeter readings every morning and evening."
C) "It's important to know the clinic's phone number in case I have questions."
D) "I will monitor my breathing and use my rescue inhaler as needed for symptoms."
E) "I'll try to avoid eating dairy products because they can make my breathing worse."
CORRECT ANSWER
A) "I need to make sure I can use my inhaler correctly to get the full dose of medication."
C) "It's important to know the clinic's phone number in case I have questions."
D) "I will monitor my breathing and use my rescue inhaler as needed for symptoms."
RATIONALE
The priority goals for discharge teaching include ensuring correct medication administration technique, providing access to resources for questions, and empowering the client to
manage acute symptoms with their prescribed rescue medication. Pulse oximetry is not a routine discharge priority for inhaled bronchodilators, and food triggers are typically
associated with other respiratory conditions or allergies, not standard asthma management.
Q2 QUESTION 2 OF 89
A nurse in a gastroenterology clinic is reinforcing teaching for a client recently prescribed sucralfate for peptic ulcer disease. The client has a history of GERD and
takes several other medications. The nurse is assessing the client's understanding of the prescribed medication regimen. Which of the following client statements
indicate appropriate understanding of sucralfate administration? (Select all that apply.)
A) "I should take this medication with a glass of milk to help it absorb better."
B) "I need to take this medication on an empty stomach, about an hour before meals."
C) "I will take this medication as needed if I experience stomach pain."
Page 1
,D) "I should ensure there are at least 2 hours between taking this and my other medications."
E) "I can take this medication with my prescribed omeprazole."
CORRECT ANSWER
B) "I need to take this medication on an empty stomach, about an hour before meals."
D) "I should ensure there are at least 2 hours between taking this and my other medications."
E) "I can take this medication with my prescribed omeprazole."
RATIONALE
Sucralfate requires an acidic environment for activation and forms a protective barrier, necessitating administration on an empty stomach and spacing from other medications to
prevent interference with absorption or efficacy.
Q3 QUESTION 3 OF 89
A client with type 1 diabetes is discussing insulin administration methods with the nurse. The client is familiar with traditional syringes and asks about the benefits of
pen devices. Which statement by the nurse accurately describes a key advantage of insulin pen delivery systems?
A) Pen devices require a longer duration of injection to ensure proper absorption.
B) The needle gauge on pen devices is typically larger for increased insulin flow.
C) Insulin pen cartridges are designed to be refilled and reused, reducing overall cost.
D) Pen devices are engineered to deliver a more precise and consistent insulin dose.
CORRECT ANSWER
D) Pen devices are engineered to deliver a more precise and consistent insulin dose.
RATIONALE
Insulin pen devices are designed with sophisticated mechanisms for accurate dose metering, ensuring a precise and consistent delivery of insulin compared to manual syringe
measurement. This precision minimizes the risk of under- or over-dosing, which is critical for glycemic control in diabetes.
Q4 QUESTION 4 OF 89
The nurse is preparing to teach a client with newly diagnosed type 2 diabetes mellitus how to self-administer the prescribed subcutaneous insulin injections. Which
instruction is essential for the nurse to include to minimize systemic absorption and maximize local efficacy?
A) Gently wash the injection site with soap and water prior to administration.
B) Rotate injection sites within the same anatomical region for each dose.
C) Apply direct, firm pressure to the injection site for 60 seconds post-administration.
D) Pinch the skin at the injection site to create a subcutaneous fold for needle insertion.
CORRECT ANSWER
D) Pinch the skin at the injection site to create a subcutaneous fold for needle insertion.
RATIONALE
Pinching the skin creates a subcutaneous fold, ensuring the insulin is injected into the subcutaneous tissue rather than intramuscularly, which optimizes absorption and prevents
tissue damage. Applying pressure or washing are not the primary methods to ensure correct tissue depth.
Q5 QUESTION 5 OF 89
A client with newly diagnosed type 2 diabetes mellitus has been prescribed an oral hypoglycemic agent. What adverse effect is most critical for the nurse to include in
client teaching regarding self-monitoring?
A) Elevated ketones in urine
B) Unintended significant weight loss
Page 2
,C) Signs of diabetic ketoacidosis
D) Symptoms of hypoglycemia
CORRECT ANSWER
D) Symptoms of hypoglycemia
RATIONALE
Oral hypoglycemics work by lowering blood glucose; therefore, the nurse must teach the client to recognize and report signs of hypoglycemia, such as shakiness or confusion, as this
is a direct and common adverse effect of the medication.
Q6 QUESTION 6 OF 89
A client diagnosed with active tuberculosis is to initiate a complex multi-drug regimen including isoniazid, rifampin, pyrazinamide, and streptomycin. The client
expresses concern, stating, "I've never had to take so many medications for an infection before." What is the nurse's MOST appropriate response to address the client's
apprehension?
A) "The other medications help prevent the side effects of streptomycin."
B) "This combination therapy is necessary because tuberculosis bacteria are very resilient."
C) "You will only need to take these medications for a short duration, about two weeks."
D) "The infection has progressed significantly, requiring this aggressive treatment approach."
CORRECT ANSWER
B) "This combination therapy is necessary because tuberculosis bacteria are very resilient."
RATIONALE
Tuberculosis is notoriously difficult to eradicate due to the resilient nature of the Mycobacterium tuberculosis organism, necessitating a prolonged and multi-drug regimen to
prevent resistance and ensure a cure. This response directly addresses the client's concern about the number of medications by explaining the inherent difficulty in treating the
infection.
Q7 QUESTION 7 OF 89
A nurse is admitting a client experiencing a severe asthma exacerbation, reporting significant dyspnea and audible wheezing. The client's current medications include
a daily inhaled corticosteroid and a short-acting beta-agonist used PRN. Which of the following interventions should the nurse prioritize immediately upon client
admission to address the acute respiratory distress? (Select all that apply.)
A) Administer prescribed bronchodilator medication.
B) Assess the client's anxiety level and coping mechanisms.
C) Educate the client on long-term asthma management strategies.
D) Encourage the client to practice pursed-lip breathing exercises.
E) Obtain a detailed family history of respiratory conditions.
F) Administer the prescribed inhaled corticosteroid.
CORRECT ANSWER
A) Administer prescribed bronchodilator medication.
D) Encourage the client to practice pursed-lip breathing exercises.
RATIONALE
Immediate pharmacologic intervention with a bronchodilator is critical for airway patency, and pursed-lip breathing can help prevent airway collapse during exhalation. Anxiety and
family history are secondary assessments, while routine education and corticosteroids are for chronic management, not acute distress.
Q8 QUESTION 8 OF 89
A client diagnosed with syphilis is prescribed penicillin G and probenecid. The nurse should explain that the probenecid is administered concurrently with penicillin
primarily to achieve which therapeutic outcome?
A) Mitigate a potential opportunistic infection that arises due to syphilis.
Page 3
, B) Enhance the anti-infective properties of penicillin by potentiating its antibacterial spectrum.
C) Suppress the development of resistant strains of Treponema pallidum.
D) Increase the duration of penicillin's action by inhibiting its renal excretion.
CORRECT ANSWER
D) Increase the duration of penicillin's action by inhibiting its renal excretion.
RATIONALE
Probenecid competes with penicillin for active tubular secretion in the kidneys, thereby delaying penicillin's excretion and prolonging its therapeutic serum concentration. This is
crucial for effectively eradicating the syphilis pathogen.
Q9 QUESTION 9 OF 89
The nurse is reviewing the prescriptions for a client newly diagnosed with a gastrointestinal disorder. The nurse should recognize that a proton pump inhibitor (PPI) is
prescribed to manage which condition?
A) Acute diarrhea
B) Persistent vomiting
C) Atrial fibrillation
D) Gastroesophageal reflux disease (GERD)
CORRECT ANSWER
D) Gastroesophageal reflux disease (GERD)
RATIONALE
Proton pump inhibitors (PPIs) are primarily indicated for conditions involving excessive gastric acid production, such as GERD, to reduce acid secretion and promote healing of
esophageal damage. The other options represent unrelated conditions.
Q10 QUESTION 10 OF 89
A client initiated on intravenous vancomycin infusion at 2000 is now reporting a new onset of tinnitus at 2230. The nurse should prioritize which immediate
intervention?
A) Administer an antiemetic to manage potential nausea.
B) Complete a full neurological assessment.
C) Discontinue the vancomycin infusion.
D) Document the client's subjective complaint.
CORRECT ANSWER
C) Discontinue the vancomycin infusion.
RATIONALE
Tinnitus is a potential ototoxic effect of vancomycin; stopping the infusion is the priority to prevent further toxicity and potential hearing loss. Documenting and assessing are
important but secondary to stopping the offending medication.
Q11 QUESTION 11 OF 89
A nurse is admitting a client with extensive full-thickness burns covering 40% of their total body surface area. The provider has prescribed famotidine 20 mg IV every
12 hours. The nurse explains to the client that this medication is a histamine H2 receptor antagonist, primarily given during the initial phase of severe burn
management. What specific complication is this medication intended to prevent in this client?
A) Diabetic ketoacidosis
B) Curling's ulcer
