,NU 185 Exam 4 | Medical-Surgical Nursing II | Galen Study Assessment 2026 UPDATE
1. A patient with a history of heart failure presents with a heart rate of 150 bpm and a narrow
QRS complex on the EKG. After vagal maneuvers fail, which medication should the nurse
prepare to administer first?
A. Amiodarone 150 mg IV push
B. Digoxin 0.25 mg IV
C. Adenosine 6 mg rapid IV push
D. Atropine 0.5 mg IV push
Answer: C
Rationale: Adenosine is the drug of choice for Supraventricular Tachycardia (SVT) to slow
conduction through the AV node. It must be given as a rapid IV push followed by a saline
flush.
2. A patient is admitted with Acute Kidney Injury (AKI). During the oliguric phase, which of
the following electrolyte imbalances is the nurse most likely to observe?
A. Hyperkalemia and Hyponatremia
B. Hypokalemia and Hypernatremia
C. Hypocalcemia and Hypophosphatemia
D. Hypercalcemia and Hyperkalemia
, Answer: A
Rationale: In the oliguric phase of AKI, the kidneys cannot excrete potassium, leading to
hyperkalemia. Dilutional hyponatremia occurs due to water retention.
3. The nurse is caring for a patient in the ICU with a CVP of 1 mmHg and a PAWP of 4 mmHg.
Which intervention is the priority?
A. Administering Furosemide 40 mg IV
B. Increasing the Nitroglycerin drip rate
C. Assisting with the insertion of an IABP
D. Administering a 500 mL Normal Saline bolus
Answer: D
Rationale: Normal CVP is 2-8 mmHg and PAWP is 6-12 mmHg. Low values indicate
hypovolemia, necessitating fluid resuscitation.
4. Which assessment finding is most indicative of the ‘compensatory’ stage of shock?
A. Narrowing pulse pressure and tachycardia
B. Cold, clammy skin and metabolic acidosis
C. Mean arterial pressure (MAP) less than 60 mmHg
D. Anuria and Mottled extremities
Answer: A
