ACUTE CARE NURSING CLINICAL EVALUATION STUDY
GUIDE SUMMER SERIES DUE JULY 2026 Q&A
1. A 68-year-old patient is admitted with septic shock. Despite fluid
resuscitation, the mean arterial pressure (MAP) remains 52
mmHg. The provider orders norepinephrine. What is the primary
mechanism of action for this vasopressor in this clinical context?
A. Beta-1 receptor agonism leading to increased cardiac
contractility only
B. Alpha-1 receptor agonism leading to systemic vasoconstriction
C. Dopaminergic receptor agonism leading to renal vasodilation
D. Beta-2 receptor agonism leading to bronchodilation and
vasodilation
Correct Answer: B
Explanation: In septic shock, norepinephrine is the first-line
vasopressor. Its primary action is potent alpha-1 agonism, causing
systemic vasoconstriction and increasing systemic vascular
resistance (SVR), which raises MAP. While it also has some beta-1
effects, the vasoconstriction is the key mechanism for increasing
MAP in this scenario. Option A is incorrect as it describes a pure
inotrope. Option C describes a low-dose dopamine effect, not
norepinephrine. Option D describes beta-2 effects, which would
cause vasodilation.
2. A nurse is caring for a patient on a mechanical ventilator with
Acute Respiratory Distress Syndrome (ARDS). The ventilator
, settings include a tidal volume of 6 mL/kg of predicted body
weight. What is the primary rationale for using this low tidal
volume strategy?
A. To prevent auto-PEEP (Positive End-Expiratory Pressure)
B. To reduce the risk of ventilator-induced lung injury (VILI) from
volutrauma
C. To improve oxygenation by allowing more time for gas exchange
D. To facilitate patient-ventilator synchrony in the assist-control
mode
Correct Answer: B
Explanation: The ARDSNet protocol advocates for low tidal volume
ventilation (6 mL/kg PBW) to prevent volutrauma, a form of VILI
caused by overdistension of alveoli. This strategy has been shown
to reduce mortality. Option A is incorrect; auto-PEEP is more
related to insufficient expiratory time. Option C is incorrect;
oxygenation is primarily managed with FiO2 and PEEP. Option D is
incorrect; synchrony is managed with sedation, mode, and flow
rates.
3. Which of the following electrocardiogram (ECG) findings is most
characteristic of Hyperkalemia?
A. Prolonged PR interval and peaked T waves
B. ST-segment elevation and pathologic Q waves
C. U waves and a prolonged QT interval
D. Deep, wide QRS complexes and flat T waves
Correct Answer: A
Explanation: Peaked, narrow-based T waves and a prolonged PR
interval are hallmark ECG signs of hyperkalemia, often appearing
, as serum potassium rises above 5.5 mEq/L. Option B is
characteristic of an ST-elevation myocardial infarction. Option C is
characteristic of hypokalemia. Option D is characteristic of severe
hyperkalemia or a bundle branch block, but peaked T waves are
the initial and most characteristic finding.
4. A patient is admitted with acute decompensated heart failure
(ADHF) and is experiencing severe dyspnea and hypoxia. The nurse
prepares to administer IV furosemide. Which assessment is critical
for monitoring the therapeutic effect of this medication?
A. Monitoring for a decrease in serum potassium levels
B. Monitoring for an increase in daily weight
C. Monitoring for a decrease in central venous pressure (CVP) and
improvement in breath sounds
D. Monitoring for an increase in blood pressure
Correct Answer: C
Explanation: Furosemide is a loop diuretic used to reduce preload
in ADHF. A therapeutic effect is indicated by a reduction in fluid
volume, which is reflected in a decreased CVP, reduced jugular
venous distention, and improved breath sounds (clearing of
crackles). Option A is a side effect, not a therapeutic effect. Option
B would indicate worsening fluid overload. Option D is not the
primary goal; while afterload reduction is part of the
management, an increase in BP would not be the primary sign of
furosemide efficacy.
, 5. A patient with acute pancreatitis has a nasogastric (NG) tube
placed for gastric decompression. The nurse notes that the patient
has a serum calcium level of 7.2 mg/dL. What pathophysiological
process best explains this hypocalcemia?
A. Third-spacing of calcium into the peritoneal cavity
B. Decreased parathyroid hormone (PTH) secretion due to
hypomagnesemia
C. Saponification (binding) of calcium with necrotic fat tissue
D. Increased renal excretion of calcium due to osmotic diuresis
Correct Answer: C
Explanation: In acute pancreatitis, lipase breaks down fats into
fatty acids, which then bind with calcium ions to form calcium
soaps in the necrotic fat tissue (saponification), leading to
hypocalcemia. The severity of hypocalcemia can correlate with the
degree of necrosis and is a poor prognostic sign. Option A is
incorrect; while third-spacing occurs, it doesn't directly lower
calcium via saponification. Option B is less direct;
hypomagnesemia can cause hypocalcemia, but saponification is
the primary cause in pancreatitis. Option D is incorrect.
6. A nurse is performing a neurologic assessment on a patient who
sustained a traumatic brain injury. The patient opens eyes only to
painful stimuli, makes incomprehensible sounds, and localizes to
pain. What is the patient's Glasgow Coma Scale (GCS) score?
A. 8
B. 9
C. 10
D. 11
