NCLEX RN Predictor Exam

1. When are manual hematocrits done?

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

2. Specific gravity in urinalysis:

Correct answer: A

Rationale: Specific gravity in urinalysis measures the concentration of solutes in urine compared to that of distilled water. This comparison helps in assessing the kidney's ability to concentrate urine properly. It is a valuable test even in dehydrated patients as it provides insights into renal function. Specific gravity can be measured using various methods, including a refractometer or reagent strips. Normal specific gravity readings of human urine typically range from 1.005 to 1.030. Choice A is correct as it accurately describes the purpose of specific gravity in urinalysis. Choices B and C are incorrect as specific gravity remains relevant in dehydrated patients and can be measured using different techniques, not solely a refractometer.

3. When evaluating the temperature of older adults, what aspect should the healthcare provider remember about an older adult's body temperature?

Correct answer: A

Rationale: When evaluating the temperature of older adults, it is important to note that their body temperature is usually lower than that of younger adults, with a mean temperature of 36.2�C. Choice B is incorrect because an older adult's body temperature is not approximately the same as that of a young child. Choice C is incorrect because body temperature is a physiological parameter and does not vary based on the type of thermometer used. Choice D is incorrect because while older adults may have less effective heat control mechanisms, their body temperature is typically lower, not widely fluctuating.

4. Which principle of body mechanics may help to reduce the risk of a back injury?

Correct answer: C

Rationale: Proper body mechanics are crucial to prevent injuries, especially for professions involving lifting and moving objects. Keeping the back straight while lifting is essential to reduce the risk of back injuries as it helps maintain the spine's natural alignment and prevents excessive strain on the back muscles. Choosing choices A, B, and D would increase the risk of back injury. Maintaining a wide base of support provides stability, bending from the knees instead of the waist protects the lower back, and pushing or pulling objects reduces the strain on the back muscles, all contributing to preventing back injuries.

5. During change-of-shift report, the nurse learns about the following four patients. Which patient requires assessment first?

Correct answer: C

Rationale: When prioritizing patient assessments, the nurse should address the patient with cirrhosis and ascites who has an elevated oral temperature of 102�F (38.8�C) first. This presentation suggests a potential infection, which is critical to address promptly in a patient with liver disease. An infection in a patient with cirrhosis can quickly progress to severe complications. The other options, such as chronic pancreatitis with abdominal pain, compensated cirrhosis with anorexia, and post-laparoscopic cholecystectomy with shoulder pain, do not indicate an immediate life-threatening situation requiring urgent assessment compared to a possible infection in a patient with cirrhosis and ascites.
