Correct Answer: A

Rationale: To auscultate for a carotid bruit, the nurse should place the stethoscope at the base of the neck, near the carotid artery. A carotid bruit is an abnormal sound that indicates turbulent blood flow in the carotid artery, potentially due to arterial narrowing or atherosclerosis. Placing the stethoscope above the clavicle, over the sternum, or over the trachea would not provide the nurse with the optimal location to assess for carotid artery abnormalities.

Correct Answer: B

Rationale: The correct answer is to assess the client's skin turgor and mucous membranes. When a client presents with severe dehydration, assessing skin turgor (elasticity of the skin) and mucous membranes (such as checking for dryness in the mouth) is crucial in determining the extent of dehydration. Encouraging the client to drink clear fluids (Choice A) may be important but assessing dehydration severity takes precedence. Monitoring vital signs (Choice C) is essential but assessing dehydration status comes first. Administering an antiemetic (Choice D) addresses vomiting but does not directly assess dehydration.

Correct Answer: A

Rationale: A pale foot with no pulse suggests a compromised blood supply, indicating a potential vascular emergency. The nurse's immediate priority is to notify the healthcare provider to address the situation promptly. Readjusting the traction, administering PRN medication, or waiting to reassess the foot later could lead to serious complications due to the compromised blood supply, making choices B, C, and D incorrect in this critical situation.

Correct Answer: D

Rationale: The best reinforcement strategy in this scenario is providing preferred activities or tokens for compliance. Positive reinforcement is effective in behavior modification programs for individuals with intellectual disabilities. Offering preferred activities or tokens serves as a reward for completing the desired behavior, in this case, oral hygiene tasks. Choices A, B, and C do not focus on reinforcing the desired behavior with positive incentives. Choice A does not provide a positive reinforcement for compliance but rather focuses on the omission of a task. Choice B uses candy, which may not be ideal for oral hygiene. Choice C involves punishment rather than positive reinforcement.

Correct Answer: A

Rationale: Gloves should be removed first as they are most likely to be contaminated. This is followed by the gown, then face shield, and mask. Correct removal sequence helps prevent contamination. Removing gloves first reduces the risk of transferring pathogens from the gloves to other PPE or surfaces. Face shield and mask should be removed last as they protect mucous membranes from exposure to contaminants. Removing PPE in the correct sequence is crucial in preventing the spread of infections.
