Correct Answer: B

Rationale: During the first trimester, it is recommended to increase caloric intake by 300 calories per day to support fetal growth and development. Choice A suggesting an increase of 600 calories is excessive and unnecessary. Choice C advising to maintain prepregnancy caloric intake could lead to inadequate nutrition for the developing fetus. Choice D recommending an increase of 150 calories is insufficient to meet the increased energy demands of pregnancy.

Correct Answer: A

Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to lie down before taking the medication. Nitroglycerin can cause a sudden drop in blood pressure leading to dizziness or fainting, so taking the medication while lying down helps prevent falls. Choice B is incorrect because nitroglycerin is usually taken on an empty stomach to enhance its absorption. Choice C is incorrect as taking a double dose of nitroglycerin can lead to low blood pressure and other adverse effects. Choice D is incorrect as nitroglycerin sublingual tablets should be stored in their original container at room temperature away from light and moisture, not in the refrigerator.

Correct Answer: A

Rationale: A continuous murmur is a classic finding in a newborn with patent ductus arteriosus. This murmur is typically heard between the first and second heart sounds and throughout systole. Absent peripheral pulses (choice B) are not typically associated with patent ductus arteriosus. Increased blood pressure (choice C) and bounding pulses (choice D) are not commonly seen with this condition. Therefore, the correct answer is A.

Correct Answer: C

Rationale: The correct intervention for a client post-bowel resection is to instruct the client to splint the incision with a pillow. This technique helps prevent dehiscence, which is the separation of wound edges, and reduces pain when coughing or moving. Splinting supports the incision site, decreasing tension on the wound. Encouraging the client to drink adequate fluids promotes hydration and aids in recovery, but a specific volume like 1,000 mL mentioned in choice A is not essential. Pain medication should be administered as needed for adequate pain control, not necessarily before every meal. Instructing the client to eat a balanced diet, including adequate protein, is crucial for wound healing and overall recovery, rather than limiting protein intake.

Correct Answer: C

Rationale: Enuresis is a common symptom of urinary tract infections in school-age children. It is often a presenting symptom due to irritation of the bladder. Periorbital edema (Choice A) is more indicative of conditions like nephrotic syndrome or renal disorders. Decreased frequency of urination (Choice B) is not typically associated with urinary tract infections. Diarrhea (Choice D) is not a common symptom of urinary tract infections but may occur due to other reasons like gastrointestinal infections.
