Nursing II Q&A with Rationale | William

1. A patient presents with a ‘blowing’ holosystolic murmur heard best at the apex and
radiating to the axilla. Which valvular disorder is most likely?
A. Aortic Stenosis
B. Mitral Regurgitation
C. Mitral Stenosis
D. Aortic Regurgitation
Correct Answer: B
Expert Explanation: Mitral regurgitation is characterized by a holosystolic murmur that is
loudest at the apex and typically radiates to the left axilla. This occurs when the mitral
valve fails to close properly during systole, allowing blood to flow back into the left atrium.
The sound is described as blowing because of the high-pressure gradient between the left
ventricle and the atrium.
2. Which of the following findings is most diagnostic of Chronic Obstructive Pulmonary
Disease (COPD) during a pulmonary function test?
A. Increased Total Lung Capacity
B. Decreased Peak Expiratory Flow
,C. Increased Oxygen Saturation on room air
D. FEV1/FVC ratio less than 0.70 post-bronchodilator
Correct Answer: D
Expert Explanation: According to the GOLD criteria, a post-bronchodilator FEV1/FVC
ratio of less than 0.70 confirms the presence of persistent airflow limitation. This ratio
indicates that the patient cannot exhale a normal percentage of their vital capacity in the
first second. This objective measurement is essential for distinguishing COPD from other
restrictive lung diseases.
3. A 65-year-old male with a history of hypertension presents with sudden onset of ‘the worst
headache of my life.’ What is the most likely diagnosis?
A. Migraine Headache
B. Cluster Headache
C. Temporal Arteritis
D. Subarachnoid Hemorrhage
Correct Answer: D
Expert Explanation: The ‘thunderclap’ headache or the description of ‘worst headache of
life’ is a classic presentation for a subarachnoid hemorrhage. This condition is a medical
emergency often caused by a ruptured cerebral aneurysm. Prompt imaging with a non-
contrast CT scan is the standard next step to confirm the diagnosis.
, 4. When assessing a patient for heart failure, the presence of an S3 gallop is often associated
with:
A. Left ventricular hypertrophy
B. Aortic valve calcification
C. Fluid overload and ventricular filling
D. Atrial contraction against a stiff ventricle
Correct Answer: C
Expert Explanation: The S3 heart sound occurs early in diastole during the rapid
ventricular filling phase. It is frequently associated with conditions of volume overload,
such as congestive heart failure. In older adults, it is almost always a pathological finding
indicating reduced ventricular compliance.
5. What is the primary mechanism of action for ACE inhibitors in the management of
hypertension?
A. Increasing sodium excretion in the distal tubule
B. Blocking the conversion of Angiotensin I to Angiotensin II
C. Antagonizing Beta-1 adrenergic receptors
D. Directly dilating peripheral arterioles
Correct Answer: B
