Correct Answer: A

Rationale: The correct answer is A: Neutrophil. Neutrophils are the most numerous type of WBC, typically comprising 50-70% of total WBC count. They are key players in the body's immune response, phagocytizing pathogens. Basophils, eosinophils, and lymphocytes are less numerous than neutrophils. Basophils are involved in allergic reactions, eosinophils combat parasitic infections, and lymphocytes play a critical role in adaptive immunity. However, in terms of sheer numbers, neutrophils outnumber the other types of WBC.

Correct Answer: C

Rationale: The correct answer is C: Eye opening, verbal response, motor response. The Glasgow Coma Scale (GCS) assesses the level of consciousness by evaluating these three factors. Eye opening assesses the patient's ability to open their eyes spontaneously or in response to stimuli. Verbal response evaluates the patient's ability to speak or respond to verbal stimuli. Motor response assesses the patient's motor function by testing responses to commands or painful stimuli. Choice A is incorrect because it includes "response to pain" instead of "verbal response." Choice B is incorrect because it includes "verbal response" instead of "eye opening." Choice D is incorrect because it includes "eye opening" instead of "verbal response." In summary, the GCS evaluates eye opening, verbal response, and motor response to determine the level of consciousness in patients.

Correct Answer: B

Rationale: The correct answer is B: Sit upright, leaning slightly forward. This position helps to minimize blood flow to the head, reducing the risk of increased bleeding. It also prevents blood from flowing down the throat, reducing the risk of aspiration. A: Lying supine with the neck extended can increase pressure on the blood vessels in the head, potentially worsening the epistaxis. C: Blowing the nose and putting lateral pressure can disrupt any clots that may have formed and increase bleeding. D: Holding the nose while bending forward at the waist can lead to blood flowing down the throat and increase the risk of aspiration.

Correct Answer: C

Rationale: The correct answer is C: Comparing the patient’s present weight with her last weight. This is the most direct and reliable method to assess volume depletion due to fluid loss. By comparing the patient's current weight with her last weight, you can easily determine if there has been a significant decrease in weight indicating fluid loss and potential hypovolemia. Explanation of why other choices are incorrect: A: Measuring the quantity and specific gravity of her urine output - This method may provide some information about hydration status, but it is not as direct or reliable as comparing weight changes. B: Taking her blood pressure - While blood pressure can indicate hypovolemia, it may not provide immediate insight into volume depletion caused by diarrhea. D: Administering the oral water test - This test is not commonly used to assess volume depletion and may not be as effective or quick as comparing weight changes.

Correct Answer: C

Rationale: The correct answer is C because it is a realistic goal for a patient with a pelvic fracture on bed rest. The patient needs to use a walker correctly to ambulate safely to the bathroom, which promotes mobility and independence while ensuring safety. This goal is specific, measurable, achievable, relevant, and time-bound. Choice A is incorrect because increasing activity level may not be safe or feasible for a patient with a pelvic fracture. Choice B is incorrect as turning every 2 hours may not be necessary or practical for this patient. Choice D is incorrect as using a sliding board may not be appropriate or necessary for someone with a pelvic fracture.
