The mother of a child who has been diagnosed with varicella asks the nurse when the child can return to school. When is the child no longer contagious?
- A. When the fever dissipates
- B. After the incubation period
- C. When the lesions have healed
- D. When the lesions are crusted over
Correct Answer: D
Rationale: The correct answer is D: 'When the lesions are crusted over.' Varicella is no longer contagious once the lesions are dry and crusted. This stage indicates that the active viral shedding has significantly decreased, reducing the risk of transmission. Choice A, 'When the fever dissipates,' is incorrect because the presence of fever does not necessarily correlate with the contagiousness of varicella. Choice B, 'After the incubation period,' is incorrect as the incubation period occurs before the onset of symptoms and is not relevant to determining contagiousness. Choice C, 'When the lesions have healed,' is incorrect as healed lesions can still be contagious if they are not crusted over.

A client with partial-thickness burns to the lower extremities is scheduled for whirlpool therapy to debride the burned area. Which intervention should the nurse implement before transporting the client to the physical therapy department?
- A. Apply a sterile dressing to the wound.
- B. Administer an analgesic.
- C. Encourage the client to drink fluids.
- D. Ensure the client's nutritional needs are met.
Correct Answer: B
Rationale: Administering an analgesic before whirlpool therapy is the priority intervention in this scenario. Whirlpool therapy for debridement can be painful for the client with partial-thickness burns. Administering an analgesic before the procedure helps manage pain during the debridement process, ensuring the client's comfort. Applying a sterile dressing (Choice A) may be necessary after the whirlpool therapy but is not the immediate pre-transport intervention. Encouraging the client to drink fluids (Choice C) and ensuring nutritional needs are met (Choice D) are important aspects of care but are not specifically related to preparing the client for whirlpool therapy.
When speaking to young parents, the nurse states that lead poisoning is one of the most common preventable health problems affecting children. What condition occurs when the level of lead ingested exceeds the amount that can be absorbed by the bone?
- A. Malnutrition
- B. Anemia
- C. Bone pain
- D. Diarrhea
Correct Answer: B
Rationale: The correct answer is B: Anemia. When the amount of lead ingested exceeds the amount that can be absorbed by the bone, it leads to anemia. Malnutrition (Choice A) is a state of inadequate nutrition, not directly related to lead poisoning. Bone pain (Choice C) is a symptom of lead poisoning due to its effects on bones but not directly related to lead ingestion exceeding absorption. Diarrhea (Choice D) is not a direct consequence of lead ingestion exceeding absorption by bones.
A client with deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin?
- A. Complete blood count (CBC)
- B. Activated partial thromboplastin time (aPTT)
- C. Prothrombin time (PT)
- D. International normalized ratio (INR)
Correct Answer: B
Rationale: The correct answer is B: Activated partial thromboplastin time (aPTT). This test is used to monitor the effectiveness of heparin therapy. A complete blood count (CBC) (choice A) is not specific for monitoring heparin therapy. Prothrombin time (PT) (choice C) and International normalized ratio (INR) (choice D) are more commonly used to monitor warfarin therapy, not heparin.
A client with ulcerative colitis is experiencing frequent diarrhea. What is the priority nursing diagnosis?
- A. Risk for impaired skin integrity
- B. Fluid volume deficit
- C. Imbalanced nutrition: less than body requirements
- D. Activity intolerance
Correct Answer: B
Rationale: The correct answer is B: Fluid volume deficit. In a client with ulcerative colitis experiencing frequent diarrhea, the priority nursing diagnosis is addressing the potential fluid volume deficit due to significant fluid loss. Maintaining adequate hydration is crucial to prevent complications associated with dehydration. While choices A, C, and D can also be concerns for a client with ulcerative colitis, addressing fluid volume deficit takes precedence as it directly impacts the client's physiological stability and can lead to serious complications if not managed promptly.
Parents of a 5-year-old child diagnosed with cognitive impairment have come to the nurse to discuss different approaches to the ongoing care of their child. The nurse should suggest focusing on what activity?
- A. Acquiring job skills
- B. Making decisions
- C. Performing self-care activities
- D. Reading and doing simple math
Correct Answer: C
Rationale: The correct answer is C: Performing self-care activities. For a 5-year-old child diagnosed with cognitive impairment, it is crucial to focus on teaching them basic self-care skills. This includes activities like dressing themselves, feeding, and personal hygiene. These skills are fundamental for their daily living and independence. Choices A, B, and D are not appropriate for a young child with cognitive impairment. Acquiring job skills is not developmentally suitable at this age, making decisions may be challenging due to cognitive limitations, and reading and doing simple math may be too advanced for their current cognitive abilities.
