A nurse is reviewing the medical records of four clients who have an acid-base imbalance. The nurse should recognize that which of the following clients is at risk for respiratory alkalosis?

A client who is taking a thiazide diuretic.

A client who is vomiting.

A client who has salicylate intoxication.

A client who has hypoventilation.

Answer and Explanation

The Correct Answer is C

The correct answer is Choice C.

Choice A rationale: Thiazide diuretics cause potassium and chloride loss, leading to metabolic alkalosis, not respiratory alkalosis. Hypokalemia decreases hydrogen ion excretion, increasing bicarbonate levels. Metabolic alkalosis is characterized by pH >7.45 and HCO₃⁻ >26 mEq/L rather than decreased PaCO₂.

Choice B rationale: Vomiting leads to metabolic alkalosis due to gastric acid loss. Hydrogen ion depletion increases bicarbonate concentration, shifting pH above normal. Arterial blood gases typically show increased HCO₃⁻ (>26 mEq/L) with a compensatory increase in PaCO₂ (>45 mmHg), not respiratory alkalosis.

Choice C rationale: Salicylate intoxication initially induces hyperventilation, reducing PaCO₂ levels below 35 mmHg and increasing pH above 7.45, leading to respiratory alkalosis. As toxicity progresses, metabolic acidosis may develop due to lactic acid accumulation, but early stages primarily present with respiratory alkalosis.

Choice D rationale: Hypoventilation leads to CO₂ retention, increasing PaCO₂ above 45 mmHg, forming carbonic acid (H₂CO₃) and causing respiratory acidosis. Blood gases show pH <7.35 with elevated PaCO₂, not respiratory alkalosis, which is caused by excessive CO₂ elimination through hyperventilation.

Correct Answer is C

Explanation

The correct answer is choice C: Verify that informed consent is obtained prior to administration. Choice A rationale: Placing the client in a semi-Fowler’s position is not specifically related to the administration of dinoprostone. This position is often used post-administration to promote comfort and labor progression, but it is not a required action prior to the administration of dinoprostone. Choice B rationale: Instructing the client to avoid urinary elimination until after administration is not necessary. There is no evidence to suggest that retaining urine affects the efficacy or safety of dinoprostone administration. Choice C rationale: Verifying that informed consent is obtained prior to administration is crucial. Dinoprostone, like any medication used to induce labor, carries potential risks and side effects. It is essential that the client is informed about these risks and consents to the procedure before the medication is administered. Choice D rationale: Allowing the medication to reach room temperature prior to administration is not a standard requirement for dinoprostone inserts. Medications have specific storage and administration guidelines that should be followed according to the manufacturer’s instructions and facility protocols.

A. Provide the client with a cool sitz bath. B. Administer methylergonovine 0.2 mg IM. C. Apply a moist, warm compress to the perineum. D. Apply povidone-iodine to the client's perineum after she voids.

Correct Answer is A

Explanation

The correct answer is choice a. Provide the client with a cool sitz bath.

Choice A rationale:

A cool sitz bath can help reduce swelling and provide pain relief for a client with a fourth-degree laceration of the perineum. Cooling the area can also help minimize inflammation and promote healing.

Choice B rationale:

Methylergonovine is typically used to prevent or treat postpartum hemorrhage by causing uterine contractions. It is not indicated for the management of perineal lacerations.

Choice C rationale:

Applying a moist, warm compress to the perineum is not recommended immediately postpartum for a fourth-degree laceration, as it can increase swelling and discomfort. Cool treatments are preferred initially.

Choice D rationale:

Applying povidone-iodine to the perineum is not a standard practice for managing perineal lacerations. It can cause irritation and is not necessary for wound care in this context.
