NUR2392/NUR 2392 Exam 2 V3 |
Multidimensional Care II (MDC 2) Q&A
with Rationale | Rasmussen University
1. A nurse is caring for a client who is scheduled for an elective surgery. The client states, ‘I
am not sure if I want to go through with this after all.’ Which action by the nurse is the
priority?
A. Explain the risks of not having the surgery to the client.
B. Reassure the client that the surgery is very common.
C. Inform the surgeon that the client has expressed doubts.
D. Ask the client to sign the consent form before they change their mind.
Correct Answer: C
Rationale: The nurse’s primary responsibility regarding informed consent is to act as a
witness and ensure the client understands the procedure. If a client expresses doubt or a
lack of understanding, the nurse must notify the surgeon so that further clarification can be
provided. This ensures that the client’s right to self-determination and informed refusal is
respected throughout the perioperative process.
2. A postoperative client is diagnosed with malignant hyperthermia. Which medication
should the nurse prepare to administer immediately?
A. Atropine sulfate
,B. Furosemide
C. Succinylcholine
D. Dantrolene sodium
Correct Answer: D
Rationale: Dantrolene sodium is a skeletal muscle relaxant that is the primary
pharmacological treatment for malignant hyperthermia. It works by interfering with the
release of calcium from the sarcoplasmic reticulum, which helps reverse the life-
threatening muscle rigidity and hypermetabolism. The nurse must also prioritize cooling
measures and monitoring the client’s temperature and vital signs during this crisis.
3. Which arterial blood gas (ABG) result should the nurse expect for a client with a history of
COPD who is experiencing exacerbation?
A. pH 7.30, PaCO2 52, HCO3 26
B. pH 7.48, PaCO2 30, HCO3 22
C. pH 7.32, PaCO2 38, HCO3 18
D. pH 7.50, PaCO2 40, HCO3 32
Correct Answer: A
Rationale: Clients with COPD often retain carbon dioxide, leading to respiratory acidosis. A
pH below 7.35 and a PaCO2 above 45 mmHg are definitive indicators of this acid-base
, imbalance. The nurse must monitor the client’s respiratory status and provide oxygen
therapy cautiously to maintain their drive to breathe.
4. A nurse is assessing a client with hypokalemia. Which of the following findings is a priority
to report to the provider?
A. Muscle weakness in the lower extremities
B. Hypoactive bowel sounds
C. Decreased deep tendon reflexes
D. Irregular heart rhythm
Correct Answer: D
Rationale: Hypokalemia can lead to life-threatening cardiac dysrhythmias due to its effect
on myocardial cell repolarization. While muscle weakness and decreased bowel sounds are
common signs, an irregular heart rhythm poses the most immediate risk to the client’s
safety. The nurse should obtain an ECG and prepare for potassium replacement therapy as
ordered.
5. Which client is at the highest risk for developing respiratory alkalosis?
A. A client with an intestinal obstruction and NG tube suctioning
B. A client with an opioid overdose
C. A client with type 1 diabetes and Kussmaul respirations
D. A client experiencing a severe panic attack
