Exam Cram NCLEX RN Practice Questions
1. Which of these specific measurements is the best index of a child's general health?
- A. Body mass index
- B. Height and weight
- C. Head circumference
- D. Chest circumference
Correct answer: B
Rationale: Height and weight are the most accurate measurements to assess a child's general health. These measurements reflect the physical growth and development of the child, indicating overall health status. Choices C and D, head circumference and chest circumference, are important measurements for specific assessments but do not provide as comprehensive an overview of general health as height and weight. Body mass index (BMI) is a calculation based on height and weight, making height and weight more direct and primary indicators of a child's health compared to BMI.
2. When examining an older adult, which technique should the nurse use?
- A. Minimize touching the patient as much as possible.
- B. Attempt to perform the entire physical examination during one visit.
- C. Speak loudly and slowly due to potential hearing deficits in aging adults.
- D. Arrange the sequence of the examination to allow as few position changes as possible.
Correct answer: D
Rationale: When examining an older adult, it is crucial to arrange the sequence of the examination to minimize position changes. This helps prevent discomfort and fatigue for the older adult, who may have mobility issues. Option A is incorrect because physical touch is essential when examining older adults, as their other senses may be diminished. Option B is incorrect as it is better to break the examination into multiple visits to ensure thoroughness and comfort. Option C is incorrect because while some older adults may have hearing deficits, it is not appropriate to assume this for all individuals without proper assessment.
3. Improper placement of the hands under the rib cage when performing the Heimlich maneuver could result in:
- A. damage to the manubrium of the sternum.
- B. damage to the xiphoid process.
- C. damage to the coccyx.
- D. None of the above is possible, even with improper hand placement.
Correct answer: B
Rationale: The xiphoid process is a small, cartilaginous extension at the inferior end of the sternum. Placing the hands improperly during the Heimlich maneuver too close to this process can result in it breaking off and potentially causing damage to internal organs. Choices A and C are incorrect because the manubrium of the sternum and the coccyx are not in the area where the hands would typically be placed during the Heimlich maneuver.
4. A leukemia patient has a relative who wants to donate blood for transfusion. Which of the following donor medical conditions would prevent this?
- A. A history of hepatitis C five years previously
- B. Cholecystitis requiring cholecystectomy one year previously
- C. Asymptomatic diverticulosis
- D. Crohn's disease in remission
Correct answer: A
Rationale: A history of hepatitis C five years previously would prevent a donor from donating blood for transfusion. Hepatitis C is a viral infection transmitted through bodily fluids, such as blood, causing inflammation of the liver. Patients with hepatitis C may not donate blood for transfusion due to the high risk of infection in the recipient. Cholecystitis requiring cholecystectomy one year previously, asymptomatic diverticulosis, and Crohn's disease in remission are not contraindications for blood donation as they do not pose a risk of transmitting infections to the recipient.
5. Specific gravity in urinalysis:
- A. compares the concentration of urine to that of distilled water
- B. is useless when the patient is dehydrated
- C. can only be measured using a refractometer
- D. None of the above
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.
