NUR2392/NUR 2392 Exam 1 V1 |
Multidimensional Care II (MDC 2) Q&A
with Rationale | Rasmussen University
1. A nurse is preparing a patient for surgery and notices the informed consent has not been
signed. What is the nurse’s primary responsibility regarding the consent form?
A. Explain the risks and benefits of the surgical procedure.
B. Provide alternatives to the planned surgery.
C. Decide if the patient is mentally competent to sign.
D. Witness the patient’s signature on the consent form.
Correct Answer: D
Rationale: The nurse’s role in the consent process is to witness the patient’s signature and
ensure the patient is signing voluntarily. The surgeon is legally responsible for explaining
the procedure, risks, benefits, and alternatives. If the patient has further questions, the
nurse must notify the surgeon to provide clarification before the signature is obtained.
2. A patient in the PACU has a respiratory rate of 8 breaths/minute and an oxygen saturation
of 88% after receiving general anesthesia. Which acid-base imbalance is this patient most at
risk for?
A. Respiratory Acidosis
B. Respiratory Alkalosis
,C. Metabolic Alkalosis
D. Metabolic Acidosis
Correct Answer: A
Rationale: Hypoventilation leads to the retention of carbon dioxide (CO2), which increases
the acid levels in the blood. This condition is known as respiratory acidosis and is common
in the immediate postoperative period due to anesthetic depression. The nurse must
monitor the patient closely and encourage deep breathing or provide supplemental oxygen
as ordered.
3. A patient is diagnosed with Malignant Hyperthermia during surgery. Which medication
should the nurse prepare to administer immediately?
A. Dantrolene Sodium
B. Atropine Sulfate
C. Epinephrine
D. Furosemide
Correct Answer: A
Rationale: Dantrolene sodium is the primary skeletal muscle relaxant used to treat
Malignant Hyperthermia. This condition is a life-threatening emergency triggered by
certain anesthetic agents that causes a rapid rise in body temperature and muscle rigidity.
In addition to administering Dantrolene, the surgical team must stop the triggering agents
and implement cooling measures.
, 4. A patient has a serum potassium level of 2.8 mEq/L. Which assessment finding is the
priority for the nurse to report?
A. Increased bowel sounds
B. Irregular heart rhythm
C. Muscle cramps in the legs
D. Generalized weakness
Correct Answer: B
Rationale: Hypokalemia, defined as a potassium level below 3.5 mEq/L, can cause life-
threatening cardiac dysrhythmias. Potassium is essential for the electrical conduction of
the heart, and low levels can lead to PVCs or cardiac arrest. While muscle weakness and
cramps are common symptoms, the stability of the heart rhythm is the highest priority.
5. The nurse is caring for a patient who is 1 day postoperative and notes the surgical dressing
is saturated with bright red blood. Which action should the nurse take first?
A. Check the patient’s most recent hemoglobin level.
B. Change the dressing and document the findings.
C. Reinforce the dressing and notify the surgeon.
D. Apply a pressure dressing and increase IV fluids.
Correct Answer: C
