NCLEX RN Predictor Exam
1. During a general survey of a patient, which finding is considered normal?
- A. Body mass index (BMI) of 20.
- B. When standing, the patient's base is narrow.
- C. The patient appears older than their stated age.
- D. Arm span (fingertip to fingertip) is greater than the height.
Correct answer: A
Rationale: A body mass index (BMI) of 20 is considered normal as the range for a normal BMI is between 19-24. When standing, a patient's base should be wide for stability and proper weight distribution. An older appearance than the stated age may indicate a history of chronic illness or chronic alcoholism. In a general survey, the patient's arm span (fingertip to fingertip) should approximately equal the patient's height. An arm span greater than the height may suggest Marfan syndrome. Therefore, the correct choice is a normal BMI of 20, which falls within the healthy range. Choices B, C, and D all describe abnormal findings that may indicate underlying health conditions or syndromes.
2. To which of the following do the CDC Standard precautions recommendations apply?
- A. Patients with diagnosed infections only
- B. Blood or body fluids with visible blood only
- C. All body fluids including sweat
- D. All patients receiving care in hospitals
Correct answer: D
Rationale: The correct answer is 'All patients receiving care in hospitals.' Standard precautions apply to all patients in healthcare settings, regardless of their infection status. These recommendations include all body fluids except sweat, non-intact skin, and mucous membranes. Choice A is incorrect as standard precautions are not limited to patients with diagnosed infections. Choice B is incorrect as standard precautions extend beyond blood or body fluids with visible blood. Choice C is incorrect as sweat is an exception to the body fluids covered under standard precautions.
3. When is a physician likely to assess turgor?
- A. When iron deficiency is suspected.
- B. When heart and lung issues are suspected.
- C. When dehydration is suspected.
- D. None of the above.
Correct answer: C
Rationale: Skin turgor is assessed when dehydration is suspected. To evaluate skin turgor, a physician pinches the skin and observes how quickly it returns to its normal position. If the skin stays folded for an extended period, it indicates dehydration. Assessing turgor helps determine a patient's hydration status. Choice A is incorrect because skin turgor is not used to assess iron deficiency. Choice B is incorrect as turgor is not related to heart and lung issues, but rather hydration status. Choice D is incorrect as turgor assessment is relevant when dehydration is suspected.
4. During an assessment, a nurse asks a patient, "If you had fever and vomiting for 3 days, what would you do?"? Which aspect of the mental status examination is the nurse assessing?
- A. Behavior
- B. Cognition
- C. Affect and mood
- D. Perceptual disturbances
Correct answer: B
Rationale: The nurse is assessing cognition in this scenario. Cognition involves evaluating a patient's judgment and decision-making abilities. By asking the patient what they would do in a specific situation, the nurse aims to determine the patient's cognitive function. A correct response indicating intact cognition would involve a decision like 'Call my doctor.' If the patient suggests inappropriate actions like 'I would stop eating' or 'I would just wait and see what happened,' it would suggest impaired judgment. The other options, behavior, affect and mood, and perceptual disturbances, refer to different aspects of the mental status examination and are not directly assessed through this question.
5. What is the correct action regarding thigh pressure when comparing it to arm pressure in an adolescent with high blood pressure?
- A. The popliteal artery should be auscultated to obtain thigh pressure.
- B. The best position to measure thigh pressure is the prone position.
- C. If the blood pressure in the arm is high in an adolescent, then it should be compared with the thigh pressure.
- D. Thigh pressure is generally higher than arm pressure due to the proximity to the heart and the size of the popliteal vessels.
Correct answer: C
Rationale: When blood pressure measured in the arm is significantly elevated, especially in adolescents and young adults, it is crucial to compare it with thigh pressure to assess for coarctation of the aorta. The popliteal artery, not the femoral artery, should be auscultated for the thigh pressure reading as the femoral artery is closer to the placement of the blood pressure cuff. Generally, thigh pressure is higher than arm pressure; however, if there is coarctation of the artery, arm pressures can be higher than thigh pressures. The preferred position for measuring thigh pressure is the prone position, not supine, with the knee slightly bent to facilitate accurate readings.
