1. A patient with acute decompensated heart failure is receiving
continuous infusion of milrinone. The nurse notes the patient’s blood
pressure has decreased from 118/72 mm Hg to 88/54 mm Hg. Which
action should the nurse take first?
A) Increase the milrinone infusion rate
B) Administer a 500 mL normal saline bolus
C) Notify the healthcare provider
D) Decrease the milrinone infusion rate
Answer: D) Decrease the milrinone infusion rate
Explanation: Milrinone is a phosphodiesterase inhibitor with inotropic
and vasodilatory effects. A significant drop in blood pressure is a
common adverse effect due to its vasodilatory properties. The most
immediate and appropriate nursing action is to reduce the infusion rate
to mitigate the hypotensive effect. While notifying the provider is
necessary, the nurse must intervene directly first. A fluid bolus might be

considered if the patient is volume depleted, but this is not the first
action. Increasing the rate would exacerbate the hypotension.
2. A patient presents with chest pain that is unrelieved by rest and
sublingual nitroglycerin. The 12-lead ECG reveals ST-segment elevation
in leads V1 through V4. Which diagnosis is most consistent with these
findings?
A) Inferior wall myocardial infarction
B) Anterior wall myocardial infarction
C) Lateral wall myocardial infarction
D) Posterior wall myocardial infarction
Answer: B) Anterior wall myocardial infarction
Explanation: ST-segment elevation in the precordial leads V1 through
V4 is indicative of an anterior wall myocardial infarction. This territory is
supplied by the left anterior descending (LAD) coronary artery. An
inferior MI is associated with leads II, III, and aVF. A lateral MI involves
leads I, aVL, V5, and V6. A posterior MI is identified by tall R waves and
ST depression in V1-V3.
3. Which hemodynamic parameter is the most reliable indicator of left
ventricular preload?
A) Central venous pressure (CVP)
B) Pulmonary artery wedge pressure (PAWP)
C) Cardiac output (CO)
,3|Page
D) Systemic vascular resistance (SVR)
Answer: B) Pulmonary artery wedge pressure (PAWP)
Explanation: PAWP, also known as pulmonary capillary wedge pressure
(PCWP), is a direct reflection of left ventricular end-diastolic pressure
(LVEDP), which is the clinical measure of left ventricular preload. CVP is
a measure of right ventricular preload. CO is a measure of cardiac
performance, and SVR is a measure of afterload.
4. A patient is on a mechanical ventilator with the following settings:
Assist-Control (AC) mode, tidal volume 500 mL, rate 14 breaths/min,
FiO2 0.40. The patient's arterial blood gas (ABG) results show pH 7.32,
PaCO2 52 mm Hg, HCO3 26 mEq/L. What is the most appropriate
nursing intervention?
A) Increase the respiratory rate
B) Decrease the FiO2
C) Increase the tidal volume
D) Suction the patient
Answer: A) Increase the respiratory rate
Explanation: The ABG results indicate respiratory acidosis (pH < 7.35,
PaCO2 > 45 mm Hg) with normal HCO3, suggesting an acute ventilatory
failure. In a patient on AC ventilation, the most direct way to increase
alveolar ventilation and lower PaCO2 is to increase the respiratory rate.
Increasing the tidal volume could also help, but increasing the rate is
, 4|Page
generally the first and safer adjustment in this scenario to avoid high
peak pressures.
5. A patient is admitted following a motor vehicle accident. The nurse
notes a flail chest segment on the left side. Which finding would
indicate the development of a life-threatening complication related to
this injury?
A) Subcutaneous emphysema
B) Paradoxical chest wall movement
C) Increased respiratory rate
D) Sudden deterioration with absent breath sounds on the left
Answer: D) Sudden deterioration with absent breath sounds on the left
Explanation: A flail chest can lead to a pulmonary contusion and, in
some cases, the rapid development of a pneumothorax or hemothorax.
A sudden deterioration in the patient's condition accompanied by
absent breath sounds on the affected side is a classic sign of a tension
pneumothorax. This is a life-threatening medical emergency requiring
immediate needle decompression or chest tube insertion. Paradoxical
movement is a characteristic finding of flail chest itself, not necessarily a
new life-threatening complication.
6. Which calcium channel blocker is most specifically indicated for the
treatment of subarachnoid hemorrhage-induced vasospasm?
A) Verapamil
