NEWEST ACTUAL EXAM 2025
QUESTIONS AND DETAILED CORRECT
ANSWERS (VERIFIED ANSWERS) WITH
RATIONALES | A+ GRADE STUDYGUIDE
A pt presents with a temperature of 105.6 F (40.9) and
nuchal rigidity. A nurse obtains blood culture and
administers antibiotics. The patient remains febrile, and
the family questions the adequacy of the interventions.
The nurse's best response should be to
A. arrange a social service consult
B. assure the family that everything will be explained later.
C suggest that the family discuss their concerns with the
physician
D. acknowledge the family's concerns while explaining
rationales for the interventions Correct Answer D. The
nurse demonstrating high levels of caring practices
and facilitation of learning will acknowledge and
address the family's learning
A pt who is newly admitted is hemodynamically stable,
had sustained a stroke and had been on mechanical
ventilation via tracheostomy tube, a continuous sedation
infusion and enteral feedings in the ICU for several days.
The pt is now off sedation and receiving O2 via a trach
collar. Gastric residual volumes of 250 ml every 6 hours
over the past 3 days have been noted. Upon collaborating
,with the nutritionist and physician, the nurse should
anticipate which of the ff
A. dilution of the enteral feeds by 50% with water
B. administration of a prokinetic agent
C. decreasing the rate of enteral feedings by 50%
D. initiation of pernteral nutrition Correct Answer B. In a
study of 206 critically ill pt, 2 or more GRVs of at least
200 mL and 1 or more GRVs of at least 250 mL were
found significantly more often in pt who experienced
frequent aspiration. Prokinetics have been advocated
to improve gastric emptying.
Which of the ff electrolye abnormalities should the PCU
nurse anticipate in caring for a pt with chronic alcohol
abuse
A. hypomagnesemia
B. hyperphosphatemia
C. hypercalcemia
D. hyponatremia Correct Answer A. Pt with chronic
alcohol abuse are at risk of reasons (1) their diet is
typically low in magnesium, (2) alcohol diuresis pulls
magnesium out of the body, and (3) there is
associated poor GI absorption of dietary magnesium
in chronic alcohol abuse.
A pt develops SVT hypotension and chest pain. The goal
of therapy will be to
A. reduce HR to increase diastolic filling time
B. produce arteriolar constriction to increase perfusion
pressure
,C. dilate coronary arteries to increase myocardial O2
delivery
D. promote venous constriction to increase preload
Correct Answer A. Rapid heart rates can lead to
hemodynamic instability, because the fast rate
prevents adequate ventricular filling during diastole
and increases myocardial oxygen demand, while
decreasing time available for coronary artery filling
Which of the following would be the most important
immediate concern when managing a pt with an acute
ischemic stroke
A. preventing pressure ulcers from limited mobility related
to hemiparesis
B. avoiding HTN while maintaining adequate cerebral
perfusion
C. performing a CT scan to evaluate for bleeding form tPA
infusion
D. intubation and mechanical ventilation for airway
protection Correct Answer B. The main goals for
managing the pt with acute ischemic stroke are
twofold: (1) enhancement of cerebral blood flow and
(2) neuroprotection, with the aim to reduce the
intrinsic vulnerability of brain tissue to ischemia
A pt with history of taking gentamicin (Garamycin) is
admitted with oliguria, confusion, lethargy, nausea and
vomiting. Lab data are as follows
BUN 26
Cr 1.6
Na 130
, K 4.9
Calcium 7.8
Which of the following should the nurse suspect
A. dehydration
B. acute tubular necrosis
C. GI infection
D. chronic renal failure Correct Answer B. This pt has
received a nephrotoxic agent, which puts the pt at risk
for development of ATN. Lab data support this
diagnosis with an elevated BUN, creatinine and
potassium. Calcium and sodium levels will be
decreased.
After a STEMI, a pt suddenly experiences a decreased
level consciousness, a weak and thready pulse and
posterior crackles in the lower half of the lung fields
bilaterally. Data are as follows
BP 76/43
HR 139
RR 24
UO 5 ml for the past hour
O2 sat 88% on 2 L via nasal (from 97%)
The nurse should suspect which of the ff causes
A. CVA
B. cardiogenic shock
c. pulmonary embolus
D. ARDS Correct Answer B. This pt has a primary risk
factor (STEMI) and signs of cardiogenic shock. The
hypotension is caused by a decrease in contractility
of cardiac muscle. Compensatory mechanisms of
tachycardia and tachypnea result. A decrease in urine
