g g g g g g g g g g g



(PPI)?
g




A) Ranitidine
B) Omeprazole
C) Diphenhydramine
D) Aluminum hydroxide g




Answer: B) Omeprazole
g g




Rationale: Omeprazole is a proton pump inhibitor used to decrease gastric acid
g g g g g g g g g g g



production, treating conditions like GERD and peptic ulcers. Ranitidine is a
g g g g g g g g g g g



histamine H2 receptor antagonist, diphenhydramine is an antihistamine, and
g g g g g g g g g



aluminum hydroxide is an antacid.

g g g




Rationale: Opioids can cause respiratory depression, making the respiratory rate
g g g g g g g g g



the most critical assessment prior to administration. Blood pressure, temperature,
g g g g g g g g g g



and weight are important, but they are secondary concerns when compared to
g g g g g g g g g g g g



respiratory function.

Answer: B) Losartan g g




Rationale: Losartan is an angiotensin II receptor blocker (ARB) used to manage
g g g g g g g g g g g



ghypertension and reduce the risk of stroke. Metformin is used for diabetes,
g g g g g g g g g g g



simvastatin for cholesterol management, and diphenhydramine is an antihistamine.

4. A patient is receiving warfarin therapy. The nurse should monitor which
g g g g g g g g g g



laboratory test to assess the effectiveness of this medication?
g g g g g g g g g




A) Hemoglobin
B) Platelet count g



C) Prothrombin time (PT) g g



D) White blood cell count g g g




Answer: C) Prothrombin time (PT)
g g g g




Rationale: Warfarin is an anticoagulant that affects clotting factors, which is
g g g g g g g g g g



gmeasured through PT. APTT (activated partial thromboplastin time) is used for
g g g g g g g g g g



gheparin therapy, while hemoglobin and platelet count are important for other
g g g g g g g g g g



gpurposes but not directly related to warfarin's effectiveness.

5. A nurse is teaching a client about the side effects of taking corticosteroids.
g g g g g g g g g g g g

g g g g g g g g g g g g



therapy?
g




A) Weight loss g



B) Hyperkalemia
C) Osteoporosis
D) Hypertension
Answer: C) Osteoporosis g g




Rationale: Long-term corticosteroid use can lead to bone demineralization,
g g g g g g g g



increasing the risk of osteoporosis. Weight loss is not typical, hyperkalemia is
g g g g g g g g g g g



more common with potassium-sparing diuretics, and hypertension can occur, but
g g g g g g g g g



gosteoporosis is a more specific side effect. g g g g g g
