The nurse is assisting the mother of a child with phenylketonuria (PKU) to select foods that are in keeping with the child's dietary restrictions. Which foods are contraindicated for this child?

A. Wheat products

B. Foods sweetened with aspartame

C. High-fat foods

D. High-calorie foods

Correct Answer: B
Rationale: The correct answer is B: Foods sweetened with aspartame. Aspartame should not be consumed by a child with PKU because it is converted to phenylalanine in the body, which can be harmful to individuals with PKU. Choice A (Wheat products) is not specifically contraindicated for PKU. Choice C (High-fat foods) and Choice D (High-calorie foods) are not typically restricted in PKU diets unless they contain high levels of phenylalanine.

A client with a history of chronic heart failure is admitted with shortness of breath. Which assessment finding is most concerning?

• A. Crackles in the lungs
• B. Shortness of breath
• C. Elevated liver enzymes
• D. Heart rate of 100 beats per minute

Correct Answer: C
Rationale: Elevated liver enzymes are concerning in a client with chronic heart failure as they may indicate liver congestion or worsening heart failure, requiring immediate intervention. While crackles in the lungs and shortness of breath are common in heart failure, elevated liver enzymes specifically point towards possible liver involvement due to heart failure. A heart rate of 100 beats per minute can be expected in a client with heart failure due to compensatory mechanisms, but elevated liver enzymes signal a more severe condition.

A client with a tracheostomy is experiencing thick, tenacious secretions. Which intervention should the nurse implement first?

• A. Encourage fluid intake to thin secretions.
• B. Administer a mucolytic agent.
• C. Increase humidity in the client's room.
• D. Perform deep suctioning as needed.

Correct Answer: C
Rationale: Increasing humidity in the client's room is the initial intervention for managing thick, tenacious secretions in a client with a tracheostomy. Adequate humidity helps to hydrate secretions, making them easier to clear, thus improving airway clearance. Encouraging fluid intake (Choice A) can be beneficial but is not the first-line intervention. Administering a mucolytic agent (Choice B) may be considered if increasing humidity alone is insufficient. Performing deep suctioning (Choice D) should be reserved for when other measures like increasing humidity have been ineffective.

A 75-year-old female client is admitted to the orthopedic unit following an open reduction and internal fixation of a hip fracture. On the second postoperative day, the client becomes confused and repeatedly asks the nurse where she is. What information is most important for the nurse to obtain?

• A. History of alcohol use
• B. Current medication list
• C. Baseline cognitive status
• D. Family history of dementia

Correct Answer: A
Rationale: The correct answer is A: History of alcohol use. In this scenario, obtaining the history of alcohol use is crucial as it could indicate withdrawal, which might explain the client's confusion. Alcohol withdrawal can lead to symptoms such as confusion, agitation, and disorientation. While knowing the current medication list (choice B) is important for overall patient care, in this case, alcohol withdrawal is a more likely cause of the confusion. Baseline cognitive status (choice C) is valuable for comparison but may not directly explain the sudden confusion. Family history of dementia (choice D) is less relevant in this acute situation compared to the potential immediate impact of alcohol withdrawal.

The healthcare provider explains through an interpreter the risks and benefits of a scheduled surgical procedure to a non-English speaking female client. The client gives verbal consent, and the healthcare provider leaves, instructing the nurse to witness the signature on the consent form. The client and the interpreter then speak together in the foreign language for an additional 2 minutes until the interpreter concludes, 'She says it is OK.' What action should the nurse take next?

• A. Ask for a full explanation from the interpreter of the witnessed discussion.
• B. Have the client sign the consent form.
• C. Document the conversation and witness the consent.
• D. Ask the client directly if she has any questions.

Correct Answer: A
Rationale: The correct action for the nurse to take next is to ask for a full explanation from the interpreter of the witnessed discussion. Verbal consent is not sufficient; it is crucial to ensure that the client fully comprehends the risks and benefits of the surgical procedure. By asking the interpreter to provide a detailed explanation of the discussion, the nurse can confirm that the client has given informed consent. Having the client sign the consent form (Choice B) without ensuring complete understanding may lead to potential misunderstandings. Documenting the conversation and witnessing the consent (Choice C) is not enough to guarantee the client's comprehension. Asking the client directly if she has any questions (Choice D) may not be effective if language barriers persist.
