Extract:
Question 1 of 5
A nurse is collecting data from a client following his first dose of captopril. The client's blood pressure is 88/60 mm Hg. Which of the following actions should the nurse take first?
Correct Answer: C
Rationale: Placing the client supine increases cerebral blood flow to counter hypotension (88/60 mm Hg) from captopril, a priority action. Standing or sitting checks could worsen symptoms, and an IV bolus is secondary.
Question 2 of 5
A nurse is collecting data from a client who received diphenhydramine for insomnia. Which of the following findings should the nurse identify as an idiosyncratic reaction?
Correct Answer: C
Rationale: Agitation is an idiosyncratic (unexpected) reaction to diphenhydramine, which typically sedates. Dry mouth, nausea, and dizziness are common side effects.
Question 3 of 5
A nurse is preparing to administer an antibiotic via intermittent IV bolus for a client who has a continuous IV infusion. Which of the following steps should the nurse take first?
Correct Answer: C
Rationale: Checking the IV site for infiltration ensures proper placement before administration, a critical first step. Hanging, wiping, and connecting follow this safety check.
Question 4 of 5
A nurse is collecting data from a client who has hypertension. The nurse should recognize that which of the following over-the-counter medications is contraindicated for this client?
Correct Answer: B
Rationale: Pseudoephedrine, a decongestant, can raise blood pressure, making it contraindicated in hypertension. Docusate, omeprazole, and guaifenesin don't significantly affect BP.
Question 5 of 5
A nurse is preparing to administer somatropin 0.24 mg/kg/week subcutaneously to be divided into six daily doses to a school-age child who weighs 66 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: 66 lb = 30 kg; 0.24 mg/kg/week = 7.2 mg/week; 7.2 mg / 6 doses = 1.2 mg/dose, rounded to 1.2 mg.
