1.
A patient presents with acute respiratory distress, audible
wheezing, and difficulty speaking in complete sentences. Which
finding most strongly indicates progression toward respiratory
failure?
A. Respiratory rate of 22/min
B. Mild expiratory wheezing
C. Increasing confusion and decreasing level of consciousness
D. Productive cough with clear sputum
Correct answer: C. Increasing confusion and decreasing level
of consciousness
Rationale: Altered mental status in a patient with respiratory
distress is a major warning sign that ventilation and
oxygenation are becoming inadequate. Hypoxemia and
hypercapnia can impair cerebral function, and decreasing
consciousness may precede respiratory arrest. A mildly elevated
respiratory rate or wheezing alone does not necessarily indicate
,impending failure. A productive cough may accompany
respiratory disease but is not, by itself, a primary indicator of
respiratory failure.
2.
Which action is most appropriate when performing a manual
blood-pressure measurement on an adult patient?
A. Place the cuff with the bladder centered over the antecubital
space
B. Position the cuff over the patient's clothing to prevent skin
irritation
C. Use a cuff whose bladder width is approximately one-half the
arm circumference
D. Position the patient's arm below heart level during
measurement
Correct answer: A. Place the cuff with the bladder centered
over the antecubital space
Rationale: Correct cuff positioning is essential for an accurate
blood-pressure measurement. The cuff bladder should be
appropriately sized and positioned over the brachial artery, with
the patient's arm supported approximately at heart level.
Measuring over clothing, using an incorrectly sized cuff, or
allowing the arm to hang below heart level can introduce error.
,3.
A patient becomes pale, diaphoretic, and hypotensive following
significant blood loss. Which physiological mechanism is
primarily responsible for the initial reduction in blood pressure?
A. Increased circulating blood volume
B. Decreased systemic vascular resistance caused by
hypervolemia
C. Reduced circulating volume and venous return
D. Increased myocardial contractility caused by hypovolemia
Correct answer: C. Reduced circulating volume and venous
return
Rationale: Hemorrhage causes a reduction in circulating
intravascular volume. This decreases venous return, preload,
stroke volume, and ultimately cardiac output. The body initially
attempts to compensate through sympathetic activation,
producing tachycardia and peripheral vasoconstriction.
Continued blood loss can overwhelm these compensatory
mechanisms and result in hypotension and shock.
4.
, Which assessment finding is most characteristic of left-sided
heart failure?
A. Dependent peripheral edema only
B. Pulmonary crackles and dyspnea
C. Enlarged liver with ascites
D. Jugular venous distention without respiratory symptoms
Correct answer: B. Pulmonary crackles and dyspnea
Rationale: Left-sided heart failure causes blood to back up into
the pulmonary circulation, producing pulmonary congestion and
symptoms such as dyspnea, orthopnea, and crackles. Right-
sided failure more commonly produces systemic venous
congestion, including peripheral edema, jugular venous
distention, hepatomegaly, and ascites. Patients can have
manifestations of both types when heart failure progresses.
5.
A patient with suspected myocardial infarction reports crushing
substernal chest pressure radiating to the jaw. Which additional
finding should increase concern for an acute coronary
syndrome?
A. Pain reproducible with light palpation over the chest wall
B. Diaphoresis accompanied by nausea
