Correct Answer: B

Rationale: A weight loss of 0.5 kg (1.1 lb) in 24 hours may indicate dehydration or malnutrition, which are critical concerns for a client receiving total parenteral nutrition (TPN). Therefore, the nurse should report this finding to the provider. Elevated blood glucose levels (Choice A) can be managed by adjusting TPN components, WBC count (Choice C) and a slightly elevated temperature (Choice D) are not directly related to TPN administration and may not require immediate intervention.

Correct Answer: B

Rationale: The correct answer is B. Metformin should be taken with a full glass of water in the morning to improve absorption and prevent gastrointestinal upset. Choice A is incorrect because metformin is not typically taken at bedtime. Choice C is unrelated to metformin therapy. Choice D is incorrect because metformin is actually better absorbed when taken with or after meals.

Correct Answer: B

Rationale: The correct answer is B: Red meat. Red meat is a good dietary source of heme iron, which is easily absorbed by the body and beneficial for individuals with iron-deficiency anemia. Oatmeal, bananas, and whole grains are not as rich in iron compared to red meat and may not provide sufficient amounts to help manage iron-deficiency anemia effectively.

Correct Answer: B

Rationale: The correct statement is B: 'Dehydration can increase the risk of preterm labor.' Dehydration can lead to increased uterine irritability, potentially causing preterm contractions and labor. Choice A is incorrect as dehydration is not treated with calcium supplements but rather with fluids. Choice C is incorrect as dehydration is not caused by decreased hemoglobin and hematocrit levels but rather by a lack of fluids. Choice D is incorrect as dehydration does not directly cause gastroesophageal reflux.

Correct Answer: D

Rationale: The correct answer is D because it provides the medication (Metoprolol), dosage (5 mg), route of administration (IV), and timing (now), making it a complete prescription. Choices A, B, and C lack either the route of administration or timing, making them incomplete prescriptions. For choice A, it lacks the route of administration, and for choices B and C, they lack the timing of administration.
