NCLEX Practice Test RN Questions
Extract:
Question 1 of 5
The nurse is preparing to administer oral potassium chloride to an elderly client. Which action should the nurse take before administering the medication?
Correct Answer: D
Rationale: Potassium chloride can worsen renal function in elderly clients. Checking the creatinine level assesses kidney function to ensure safe administration. Glucose hypocalcemia and withholding food are not directly related to potassium administration.
Question 2 of 5
The nurse is caring for a client with a history of a hiatal hernia who is receiving Propulsid (cisapride). The nurse should monitor the client for:
Correct Answer: A
Rationale: Cisapride can prolong the QT interval, risking arrhythmias, requiring cardiac monitoring. Hypotension, constipation, and weight gain are not primary side effects.
Question 3 of 5
The nurse is caring for a newborn with a suspected diaphragmatic hernia. The nurse should:
Correct Answer: D
Rationale: Positioning a newborn with a diaphragmatic hernia on the affected side facilitates lung expansion on the unaffected side, improving respiration. Trendelenburg worsens breathing, and fluids are secondary.
Question 4 of 5
When a client is receiving vasoactive therapy IV, such as dopamine (Intropin), and extravasation occurs, the nurse should be prepared to administer which of the following medications directly into the site?
Correct Answer: A
Rationale: Phentolamine is given to counteract the-adrenergic effects that cause ischemia and necrosis of local tissue. Epinephrine is an endogenous catecholamine that produces vasoconstriction and increases heart rate and contractility. Phenylephrine causes constriction of arterioles of skin, mucous membranes, and viscera, which in turn can cause ischemia and necrosis. Sodium bicarbonate is an alkalinizing agent that is incompatible with dopamine.
Question 5 of 5
A client is taking Rifadin (rifampin) 600 mg PO daily for pulmonary tuberculosis. The nurse should tell the client to:
Correct Answer: B
Rationale: Rifampin causes harmless red-orange discoloration of urine, sweat, and tears, which clients should be informed about to avoid alarm. It can be taken with or without food, timing is not restricted to bedtime, and it is taken daily, not conditionally.
