1. The registered nurse (RN) is reviewing the assignment for a medical-
surgical unit. Using the Maslow’s Hierarchy of Needs framework for
prioritization, which client should the nurse assess first?
A) An older adult client with chronic osteoarthritis who reports severe joint
pain rated as an 8 out of 10.
B) A client with an acute asthma exacerbation who has an arterial
oxygen saturation (SaO₂) of 88%.
C) A client newly diagnosed with terminal pancreatic cancer who is weeping
and expressing severe anxiety.
D) A postoperative client who underwent an open cholecystectomy 48 hours
ago and has an intact, dry surgical dressing.
CORRECT ANSWER: B
RATIONALE: Physiological needs—specifically airway, breathing, and
circulation (ABCs)—take absolute precedence over psychosocial, safety, or
chronic pain needs. An acute asthma exacerbation with an SaO₂ of 88%
indicates severe hypoxemia and potential respiratory failure, requiring immediate
oxygenation and bronchodilator intervention. Option A represents severe pain,
,which is a priority but subordinate to airway and oxygenation. Option C represents
a profound psychosocial need, which should be addressed after physiological
stability is achieved. Option D is a stable postoperative client who does not require
immediate, emergent assessment.
2. A client diagnosed with major depressive disorder has been taking
phenelzine, a monoamine oxidase inhibitor (MAOI), for three weeks. During
a home health visit, the client reports a sudden, throbbing occipital headache
and neck stiffness. What is the priority action by the RN?
A) Instruct the client to take a dose of acetaminophen and rest in a dark,
quiet room.
B) Check the client's blood pressure immediately and arrange
transportation to the emergency department.
C) Reassure the client that head pain is a common, transient side effect
during the first month of therapy.
D) Evaluate the client’s serum lithium level to rule out concurrent drug-
induced toxicity.
CORRECT ANSWER: B
RATIONALE: MAOIs like phenelzine interact with tyramine-rich foods and
certain medications to trigger a hypertensive crisis, a medical emergency. Classic
manifestations include a severe, throbbing occipital headache, neck stiffness,
tachycardia, and markedly elevated blood pressure. The priority is to assess the
blood pressure immediately and seek emergency medical care to prevent
intracranial hemorrhage. Administering an analgesic (Option A) or dismissing the
symptom as a minor side effect (Option C) delays critical treatment. Lithium levels
(Option D) are unrelated to MAOI therapy complications.
3. The RN is planning care for a client with acute pancreatitis. Which
physiological rationale supports keeping this client on a strict nothing by
mouth (NPO) status?
A) To minimize the risk of fluid volume overload and pulmonary edema.
B) To reduce the secretion of pancreatic enzymes and allow the
inflamed organ to rest.
C) To prevent the development of a secondary bacterial infection within the
biliary tract.
D) To promote the hepatic synthesis of fat-soluble vitamins and clotting
factors.
, CORRECT ANSWER: B
RATIONALE: The primary goal of managing acute pancreatitis is to halt the
auto-digestion of the organ caused by prematurely activated digestive enzymes.
Maintaining an NPO status prevents the release of cholecystokinin and secretin,
which in turn minimizes pancreatic enzyme secretion and promotes tissue rest.
Option A is incorrect because clients with pancreatitis require aggressive fluid
resuscitation, not fluid restriction. Options C and D are not the physiological
mechanisms or reasons for withholding oral intake in this acute disorder.
4. The nurse is caring for a child who is experiencing a severe anaphylactic
reaction after receiving an intravenous antibiotic. After immediately
stopping the medication infusion, which medication should the nurse prepare
to administer first-line?
A) Methylprednisolone intravenously
B) Diphenhydramine intramuscularly
C) Epinephrine subcutaneously or intramuscularly
D) Albuterol via continuous nebulization
CORRECT ANSWER: C
RATIONALE: Epinephrine is the absolute first-line drug of choice for treating
anaphylaxis. It acts rapidly as an alpha-adrenergic agonist to reverse peripheral
vasodilation and hypotension, and as a beta-adrenergic agonist to cause
bronchodilation and stabilize mast cells. Antihistamines like diphenhydramine
(Option B) and corticosteroids like methylprednisolone (Option A) are secondary
treatments that do not act fast enough to reverse life-threatening upper airway
obstruction or circulatory collapse. Albuterol (Option D) targets lower airway
bronchospasm but does not address systemic vasodilation or laryngeal edema.
5. While reviewing the laboratory results for an adult client with advanced
liver cirrhosis, the RN notes a serum ammonia level of 110 mcg/dL
(normal: 15–45 mcg/dL). Which clinical complication should the nurse
monitor for based on this finding?
A) Widespread mechanical muscle rigidity and structural bone fractures.
B) Hepatic encephalopathy, manifested by altered mental status and
asterixis.
C) Severe cardiac dysrhythmias secondary to a prolonged QT interval.
D) Acute hemolytic anemia resulting from splenic sequestration of red blood
cells.
, CORRECT ANSWER: B
RATIONALE: An elevated serum ammonia level is a primary driver of hepatic
encephalopathy in clients with cirrhosis, as the failing liver cannot convert
ammonia into urea. Ammonia crosses the blood-brain barrier, causing
neurotoxicity that manifests as confusion, lethargy, slurred speech, and asterixis
(flapping tremors of the hands). Options A, C, and D are not direct clinical
consequences of hyperammonemia.
6. An RN is evaluating an infant diagnosed with hypertrophic pyloric
stenosis. Which clinical feature is considered pathognomonic or classic for
this specific pediatric gastrointestinal disorder?
A) Intermittent, jelly-like bloody stools containing mucus and sloughed
tissue.
B) Projectile, nonbilious vomiting immediately following a feeding
accompanied by a palpable olive-shaped mass.
C) Severe abdominal distention with visible loops of the colon and fecal
emesis.
D) Constant, low-volume regurgitation triggered exclusively by changes in
positioning.
CORRECT ANSWER: B
RATIONALE: Hypertrophic pyloric stenosis involves hypertrophy of the
circular muscle of the pylorus, causing gastric outlet obstruction. The classic
clinical presentation includes forceful, projectile, nonbilious vomiting because
the blockage is proximal to the bile duct, along with a palpable olive-shaped mass
in the right upper quadrant. Option A describes intussusception. Option C
suggests a lower intestinal obstruction. Option D is typical of mild
gastroesophageal reflux.
7. The nurse is checking a client who underwent a subtotal thyroidectomy 12
hours ago. The client reports a tingling sensation around the mouth and
fingers, and the nurse notes muscle twitching upon tapping the facial nerve.
Which medication should the nurse anticipate administering?
A) Potassium chloride intravenously
B) Calcium gluconate intravenously
C) Levothyroxine sodium orally
D) Calcitonin subcutaneously
