Correct Answer: D

Rationale: The correct answer is D: Serum albumin 3.5 g/dL. A low serum albumin level indicates protein deficiency, which can be a complication of TPN therapy and requires prompt intervention. The other laboratory findings provided (serum calcium 8.5 mg/dL, blood glucose level 120 mg/dL, and serum sodium 138 mEq/L) are within normal ranges and do not specifically indicate complications related to TPN therapy.

Correct Answer: B

Rationale: The correct answer is B because the client should exhale quickly and forcefully into the peak flow meter after taking a deep breath to measure peak expiratory flow.
Choice A is incorrect as blowing as hard as possible may not provide an accurate reading.
Choice C is incorrect because inhaling deeply before blowing can affect the results.
Choice D is incorrect as holding the breath before exhaling is not part of using a peak flow meter.

Correct Answer: C

Rationale: Correct! Dry mucous membranes are a common finding in clients with dehydration. Dehydration leads to reduced fluid volume in the body, resulting in dryness of mucous membranes, decreased skin turgor, and thirst. Bradycardia (slow heart rate) is not typically associated with dehydration, as the body tries to compensate for decreased fluid volume by increasing heart rate. Hypotension (low blood pressure) is a possible finding in dehydration due to reduced circulating volume. Tachypnea (rapid breathing) is more commonly seen in conditions like respiratory distress or metabolic acidosis, rather than dehydration.

Correct Answer: B

Rationale: The correct answer is B: 'Sleep with the head of your bed elevated.' Elevating the head of the bed helps reduce acid reflux by keeping the head higher than the stomach, preventing stomach acid from flowing back into the esophagus.

Choices A, C, and D are incorrect. Avoiding eating small, frequent meals, lying down after eating, and drinking fluids with meals can exacerbate GERD symptoms by increasing stomach acid production and promoting acid reflux.

Correct Answer: A

Rationale: Spinach is the correct answer because it is a good source of calcium. Since the client has eliminated dairy products due to lactose intolerance, which are a common source of calcium, increasing spinach consumption can help compensate for the lost calcium. Peanut butter, ground beef, and carrots are not significant sources of calcium and therefore not the best choice for this client.
