1. A nurse is administering furosemide (Lasix) to a client with heart failure. Which of the
following is a priority assessment for the nurse to make before administering this
medication?
A) Assessing the client’s blood pressure
B) Checking the client’s potassium level
C) Monitoring the client’s respiratory rate
D) Assessing the client’s sodium level
Answer: B) Checking the client’s potassium level
Rationale: Furosemide is a loop diuretic that can cause the excretion of potassium, potentially
leading to hypokalemia. The nurse must check the potassium level before administering this
medication. Hypokalemia can lead to serious complications, such as arrhythmias.
2. A client with hypertension is prescribed lisinopril (Zestril). The nurse knows that this
medication works by:
A) Blocking the release of aldosterone
B) Blocking the effects of norepinephrine
C) Inhibiting the angiotensin-converting enzyme (ACE)
D) Relaxing blood vessels directly
Answer: C) Inhibiting the angiotensin-converting enzyme (ACE)
,Rationale: Lisinopril is an ACE inhibitor that works by blocking the enzyme that converts
angiotensin I to angiotensin II, a substance that constricts blood vessels. This results in
vasodilation and a decrease in blood pressure.
3. A nurse is teaching a client about the use of warfarin (Coumadin). Which of the
following should the nurse include in the teaching plan?
A) "You will need to have your blood clotting time checked regularly."
B) "Avoid taking any aspirin or aspirin-containing products."
C) "Eat a high-protein diet to prevent bleeding."
D) "You will not need to have your blood monitored once you're stabilized."
Answer: A) "You will need to have your blood clotting time checked regularly."
Rationale: Warfarin is an anticoagulant that requires regular monitoring of the International
Normalized Ratio (INR) or prothrombin time (PT) to ensure therapeutic levels and to avoid
bleeding or clotting risks.
4. A client is prescribed albuterol for asthma. The nurse knows that albuterol works by:
A) Blocking leukotriene receptors
B) Relaxing the smooth muscle of the airways
C) Increasing mucus production in the lungs
D) Decreasing the production of histamine
Answer: B) Relaxing the smooth muscle of the airways
Rationale: Albuterol is a short-acting beta-agonist that works by stimulating beta-2 receptors in
the bronchial smooth muscle, leading to bronchodilation and easing the client’s breathing.
5. The nurse is administering insulin to a client with type 1 diabetes. The nurse
understands that insulin is primarily used to:
A) Stimulate the production of glucose from glycogen
B) Prevent protein breakdown
C) Lower blood glucose levels
D) Raise blood glucose levels
Answer: C) Lower blood glucose levels
, Rationale: Insulin is a hormone that helps lower blood glucose levels by facilitating the entry of
glucose into cells for energy or storage as glycogen in the liver and muscles.
6. A nurse is caring for a patient receiving digoxin (Lanoxin) for heart failure. Which of the
following is a priority assessment for the nurse to make before administering this
medication?
A) Blood pressure
B) Potassium level
C) Respiratory rate
D) Temperature
Answer: B) Potassium level
Rationale: Digoxin is a cardiac glycoside that can increase the risk of toxicity if the potassium
level is low. Hypokalemia can make the heart more susceptible to digoxin toxicity, which may
cause life-threatening arrhythmias. The nurse should check the potassium level before
administering the drug.
7. A client is receiving morphine sulfate for pain management. The nurse should closely
monitor for which of the following adverse effects?
A) Diarrhea
B) Hyperventilation
C) Constipation
D) Hypertension
Answer: C) Constipation
Rationale: Opioid analgesics like morphine can cause constipation due to their effect on the
gastrointestinal system. Nurses should educate clients about this potential side effect and suggest
measures to prevent constipation, such as increased fluid intake and fiber.
8. A nurse is providing discharge teaching for a client who has been prescribed an SSRI
(selective serotonin reuptake inhibitor), such as fluoxetine (Prozac). Which of the following
statements by the client indicates a need for further teaching?
A) "I should expect some improvement in my mood within the next 1-2 weeks."
B) "I will stop the medication if I feel better after a few days."
