Correct Answer: D

Rationale: Hyperemesis gravidarum, characterized by severe nausea and vomiting, leads to dehydration and electrolyte imbalances. The priority intervention is initiating IV fluids to correct these imbalances. Providing emotional support is important for the client's well-being, but addressing fluid and electrolyte imbalances takes precedence. Monitoring daily weight and encouraging small frequent meals are beneficial interventions but are not the priority when managing hyperemesis gravidarum.

Correct Answer: D

Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.

Correct Answer: B

Rationale: The correct answer is B: 'Murmur.' A murmur is a swishing sound heard during auscultation, typically caused by turbulent blood flow through the heart or valves. Choices C and D, 'S3 sound' and 'S4 sound,' refer to specific heart sounds associated with different cardiac conditions, not the general description of a swishing sound. Choice A, 'Heart murmur,' is redundant as 'murmur' alone is sufficient to describe the swishing sound heard.

Correct Answer: D

Rationale: The correct answer is D. Clients taking warfarin should avoid alcohol and over-the-counter medications without consulting their healthcare provider, as these can interact with warfarin and increase the risk of bleeding. Aspirin, in particular, can exacerbate this risk. Choice A is incorrect because taking warfarin with aspirin can increase the risk of bleeding. Choice B is incorrect as while green leafy vegetables contain vitamin K which can interact with warfarin, it is more important to maintain a consistent intake rather than increase it. Choice C is incorrect because foods high in potassium do not directly impact the bleeding risk associated with warfarin.

Correct Answer: B

Rationale: The correct strategy for teaching a client with low literacy about a new diagnosis of hypertension is to use simple language and visual aids. This approach helps ensure better understanding of the diagnosis and treatment plan by making the information clear and accessible. Providing a detailed handout with complex terms (Choice A) would not be suitable as it may confuse the client further. Encouraging the client to research the diagnosis online (Choice C) could lead to misinformation and overwhelm the client with information they may not understand. Incorporating medical jargon to explain the condition (Choice D) would not be helpful for a client with low literacy as it may complicate rather than clarify the information.
