NUR2356 Exam 3: Multidimensional Care I
(MDC1) Verified & Updated Questions and
Answers - Rasmussen University
1. A patient presents with a serum potassium level of 6.2 mEq/L. Which nursing
intervention is the highest priority?
A. Check the patient’s blood pressure
B. Place the patient on a cardiac monitor
C. Encourage intake of bananas and orange juice
D. Administer a potassium-sparing diuretic
Answer: B
Explanation: Hyperkalemia (K+ > 5.0) can cause life-threatening cardiac dysrhythmias.
Monitoring the heart rhythm is the priority action.
2. Which clinical manifestation is most characteristic of hypocalcemia?
A. Constipation and kidney stones
B. Decreased deep tendon reflexes
C. Positive Trousseau’s sign
D. Muscle weakness and lethargy
Answer: C
Explanation: Hypocalcemia causes neuromuscular excitability, leading to signs like
Trousseau’s (carpal spasm) and Chvostek’s sign.
,3. An arterial blood gas (ABG) shows pH 7.32, PaCO2 50 mmHg, and HCO3 24
mEq/L. How does the nurse interpret this result?
A. Respiratory Acidosis
B. Metabolic Alkalosis
C. Metabolic Acidosis
D. Respiratory Alkalosis
Answer: A
Explanation: A low pH (< 7.35) indicates acidosis, and a high PaCO2 (> 45) indicates a
respiratory cause.
4. A patient with prolonged vomiting is at risk for which acid-base imbalance?
A. Respiratory Acidosis
B. Metabolic Acidosis
C. Metabolic Alkalosis
D. Respiratory Alkalosis
Answer: C
Explanation: Vomiting causes the loss of gastric acid (HCl), which leads to an increase in
the body’s pH (alkalosis) of metabolic origin.
5. What is the primary responsibility of the nurse when obtaining informed
consent for surgery?
A. Witnessing the patient’s signature on the form
B. Ensuring the patient is fully informed by the surgeon
C. Explaining the risks and benefits of the procedure
D. Deciding if the patient should have the surgery
Answer: A
Explanation: The surgeon is responsible for the explanation; the nurse acts as a witness to
the patient’s signature and ensures they are competent to sign.
, 6. During the intraoperative phase, which member of the surgical team is
responsible for maintaining the sterile field?
A. Scrub Nurse
B. Circulating Nurse
C. Anesthesiologist
D. Recovery Room Nurse
Answer: A
Explanation: The scrub nurse or surgical technologist remains within the sterile field,
while the circulating nurse works outside of it.
7. A postoperative patient is experiencing a sudden onset of chest pain and
shortness of breath. What should the nurse suspect?
A. Atelectasis
B. Pulmonary Embolism
C. Hypovolemic Shock
D. Pneumonia
Answer: B
Explanation: Chest pain and dyspnea post-surgery are classic signs of a pulmonary
embolism, a major complication of DVT.
8. Which vision condition is characterized by a clouding of the lens, causing
blurred vision and sensitivity to glare?
A. Glaucoma
B. Retinal Detachment
C. Macular Degeneration
D. Cataracts
Answer: D
Explanation: Cataracts involve opacity (clouding) of the lens, which blocks light and blurs
vision.
