A nurse is educating a client about caloric intake and weight reduction. Which of the following client statements indicates an understanding of the teaching?

Correct Answer: A

Rationale: The correct answer is A: 'If I eat 500 fewer calories per day, I should lose 1 pound per week.' This statement is accurate because a reduction of 500 calories per day typically results in a weight loss of 1 pound per week. This is based on the principle that a calorie deficit of 3,500 calories equals about 1 pound of body fat. Choices B, C, and D are incorrect because they do not align with the established relationship between calorie reduction and weight loss. Eating 450 fewer calories per day would not lead to a weight loss of 2 pounds per week; similarly, reducing calories by 250 or 300 per day would not result in losing 2 pounds or 1 pound per week, respectively.

Correct Answer: B

Rationale: The correct intervention for a client experiencing alcohol withdrawal is to administer lorazepam. Lorazepam, a benzodiazepine, is commonly used to manage the symptoms of alcohol withdrawal by preventing seizures and reducing agitation and anxiety. Encouraging frequent ambulation (choice A) may not be safe during alcohol withdrawal due to potential instability and confusion. Providing a low-calorie diet (choice C) is not a priority during alcohol withdrawal, as the focus is on managing withdrawal symptoms. Administering insulin as prescribed (choice D) is unrelated to managing alcohol withdrawal symptoms.

Correct Answer: C

Rationale: High-pitched bowel sounds are often heard early in a small bowel obstruction due to increased peristalsis as the bowel tries to overcome the blockage. Choices A, B, and D are incorrect. Abdominal distention is more commonly associated with large bowel obstructions, while large bowel movements and copious vomiting are not typical findings in small bowel obstructions.

Correct Answer: D

Rationale: The correct answer is D because transporting a stable child to x-ray is a task that can be safely delegated to an assistive personnel. This task does not require clinical judgment or specialized skills. Choices A, B, and C involve assessments and interventions that require nursing judgment and should be performed by a qualified nurse. Initiating a dietary consult for a toddler involves assessing the child's nutritional needs and must be done by a nurse. Administering a glycerin suppository to a preschool-age child requires medication administration skills and knowledge of appropriate dosages, which are within the nurse's scope of practice. Evaluating gastric residual following intermittent feeding of an adolescent is a clinical assessment that requires interpretation and decision-making based on the findings, making it a nursing responsibility.

Correct Answer: C

Rationale: The correct action the nurse should take when administering enoxaparin is to inject the medication in the abdomen subcutaneously. This route ensures proper absorption of the medication. Aspiration is not necessary before injecting enoxaparin as it is a subcutaneous injection, not an intramuscular injection. Massaging the site after injecting should be avoided to prevent bruising. Enoxaparin injections are typically given at a 45 to 90-degree angle, not necessarily at a strict 90-degree angle.

Correct Answer: B

Rationale: The correct action for the nurse to take first when a client with a nasogastric tube reports feeling nauseated is to check the client's bowel sounds. This assessment helps the nurse evaluate for possible complications, such as a blockage or decreased gastric motility, that could be causing the nausea. Administering an antiemetic (Choice A) should not be the first action without assessing the underlying cause of the nausea. Slowing the rate of the feeding (Choice C) may be appropriate but is not the priority until further assessment is done. Placing the client in a supine position (Choice D) is not typically indicated for managing nausea in this situation.

Correct Answer: B

Rationale: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.

Correct Answer: B

Rationale: The correct answer is B: A chicken breast. Chicken breast is low in potassium, making it a safe option for clients with chronic kidney disease who need to limit their potassium intake. Foods like bananas and orange juice are high in potassium, which should be avoided or limited by individuals with chronic kidney disease to prevent further kidney damage.

Correct Answer: C

Rationale: The correct answer is C: 'Support your weight on your hands.' When using crutches, it is important to support your weight on your hands rather than underarms to prevent injury to the axillary nerves and blood vessels. Placing weight on the underarms can lead to nerve damage and circulatory issues. Choices A, B, and D are incorrect. Keeping the elbows extended when walking is important for stability, holding the crutches slightly in front of you allows for proper balance, and supporting weight on the hands maintains the correct weight-bearing position.
