Correct Answer: C

Rationale: In clients with Syndrome of Inappropriate Antidiuretic Hormone (SIADH), the nurse should expect hyponatremia. SIADH leads to excess water retention, diluting the sodium levels in the blood, resulting in low serum sodium levels. Choice A, increased urine output, is incorrect as SIADH causes water retention, leading to decreased urine output. Choice B, increased serum sodium, is incorrect because SIADH causes a dilutional effect due to water retention, resulting in decreased serum sodium levels. Choice D, hypercalcemia, is unrelated to SIADH and not a typical finding.

Correct Answer: B

Rationale: Placing the client in a private room is the appropriate infection control measure for C. difficile to prevent the spread of infection. While wearing a face shield may be necessary for procedures that generate splashes or sprays, it is not the primary precaution for C. difficile. Negative pressure rooms are typically used for airborne infections, not for C. difficile. Using an alcohol-based hand rub is important for hand hygiene but is not specific to managing C. difficile infection.

Correct Answer: A

Rationale: Limiting fluid intake is essential in managing patients with chronic kidney disease to prevent fluid overload, which can worsen kidney function. Increasing potassium intake is not recommended as patients with kidney disease often need to limit potassium. Providing a high-protein diet may put extra strain on the kidneys, so it is not ideal. Administering IV antibiotics is not a standard treatment for chronic kidney disease.

Correct Answer: A

Rationale: The correct answer is Hypokalemia. Furosemide, a loop diuretic, can lead to potassium depletion in the body, causing hypokalemia. This is a significant concern as low potassium levels can result in cardiac arrhythmias and other serious complications. Hyperkalemia (Choice B) is unlikely to occur as a result of furosemide use. Hyponatremia (Choice C) is more commonly associated with thiazide diuretics. Hypercalcemia (Choice D) is not typically linked to furosemide use.

Correct Answer: D

Rationale: During early pregnancy, nausea and vomiting are common. Instructing the client to eat dry carbohydrates like crackers before getting out of bed can help alleviate these symptoms. This recommendation helps prevent an empty stomach, which can worsen nausea. High-protein foods (Choice A) may be harder to digest and could exacerbate nausea. Lying down after meals (Choice B) may increase gastric reflux and worsen symptoms. Drinking water with meals (Choice C) may make the client feel fuller, potentially worsening nausea.
