Extract:
Question 1 of 5
A nurse is caring for a client who has diabetes insipidus. Which of the following medications should the nurse plan to administer?
Correct Answer: D
Rationale: Desmopressin, a synthetic ADH, treats diabetes insipidus by reducing urine output. Lithium and furosemide worsen it, and insulin is for diabetes mellitus.
Question 2 of 5
A nurse is caring for a client who has an IV in the left forearm and whose infusion pump has alarmed several times. Which of the following actions should the nurse take first?
Correct Answer: C
Rationale: Repositioning the arm addresses common infusion pump alarms caused by tubing occlusion from arm position, the most likely issue.
Question 3 of 5
A nurse is assessing a client for a positive Chvostek's sign following a thyroidectomy. Which of the following areas on the client's head should the nurse tap to assess the client for tetany?
Correct Answer: B
Rationale: Tapping 2 cm in front of the ear over the facial nerve tests for Chvostek's sign, indicating hypocalcemia post-thyroidectomy.
Question 4 of 5
A nurse is caring for a group of clients. The nurse should obtain a blood pressure reading using only the left extremity from which of the following clients?
Correct Answer: B
Rationale: Blood pressure measurement on an arm with an arteriovenous fistula risks damage; the left arm is used instead. PICC lines, weakness, or Bell's palsy do not contraindicate BP measurement.
Question 5 of 5
A nurse is reviewing the following ABG results for a postoperative client: pH 7.27, PaCO2 49 mm Hg, PaO2 65 mm Hg, HCO 22 mEq/L. The nurse should interpret the findings as which of the following imbalances?
