Exam Cram NCLEX RN Practice Questions
1. What type of blood pressure measurement error is most likely to occur if the nurse does not check for the presence of an auscultatory gap?
- A. Diastolic blood pressure may not be heard.
- B. Diastolic blood pressure may be falsely low.
- C. Systolic blood pressure may be falsely low.
- D. Systolic blood pressure may be falsely high.
Correct answer: C
Rationale: If an auscultatory gap is undetected, a falsely low systolic reading may occur. This gap can lead to an underestimation of the systolic blood pressure, causing potential misinterpretation of the patient's condition. The diastolic blood pressure may not be heard due to the gap, but the critical issue in this scenario is the risk of underestimating systolic blood pressure, which can impact clinical decision-making. Choices B, C, and D are incorrect because the key concern in this context is the potential for a falsely low systolic blood pressure reading when an auscultatory gap is not assessed.
2. The nurse is assessing an 80-year-old male patient. Which assessment finding would be considered normal?
- A. Decrease in body weight from his younger years
- B. Decrease in deposits of fat in the cheeks and forearms
- C. Presence of kyphosis and flexion in bilateral knees and hips
- D. Change in overall body proportion, including a longer trunk and shorter extremities
Correct answer: C
Rationale: In an 80-year-old male patient, the presence of kyphosis (rounded upper back) and flexion in bilateral knees and hips are considered normal age-related changes. These postural changes are commonly seen in older adults due to structural changes in the spine and joints. Option A is incorrect as aging individuals typically experience a decrease in body weight, not an increase. Option B is also incorrect as there is usually a decrease in subcutaneous fat from the face and periphery, rather than an increase in fat deposits in specific areas. Option D is incorrect because the change in overall body proportion with aging usually involves a shorter trunk and relatively longer extremities, not the other way around. This is because long bones do not shorten with age, leading to this characteristic change in body proportions.
3. What technique would the nurse use to accurately assess a rectal temperature in an adult?
- A. Use a lubricated blunt tip thermometer.
- B. Insert the thermometer 2 to 3 inches into the rectum.
- C. Leave the thermometer in place for up to 8 minutes if the patient is febrile.
- D. Wait 2 to 3 minutes if the patient has recently smoked a cigarette.
Correct answer: A
Rationale: To accurately assess a rectal temperature in an adult, a nurse should use a lubricated rectal thermometer with a short, blunt tip. The thermometer is inserted only 2 to 3 cm (1 inch) into the rectum and left in place for 2 minutes. Choice B is incorrect as inserting the thermometer 2 to 3 inches would be too deep and inaccurate. Choice C is incorrect as leaving the thermometer in place for up to 8 minutes is unnecessary and can cause discomfort. Choice D is incorrect as smoking a cigarette does not impact rectal temperatures.
4. You have been assigned to take an apical pulse for one of the patients on the nursing unit. How will you do this?
- A. You will place the stethoscope over the heart and listen for any irregular beats.
- B. You will place the stethoscope over the heart and count the beats per minute.
- C. You will place your fingertip over the patient's wrist and feel for any irregular beats.
- D. You will place your fingertip over the patient's wrist and count the beats per minute.
Correct answer: B
Rationale: To take an apical pulse accurately, you should place the stethoscope over the heart and count the number of beats per minute. This method provides a precise assessment of the heart rate. While listening for irregular beats is essential for assessing the heart's rhythm, the primary objective of taking an apical pulse is to determine the heart rate. Choices C and D are incorrect because the apical pulse is not taken at the wrist; instead, it is obtained by auscultating at the apex of the heart, usually at the point where the fifth intercostal space meets the midclavicular line.
5. A child is admitted to the hospital several days after stepping on a sharp object that punctured her athletic shoe and entered the flesh of her foot. The physician is concerned about osteomyelitis and has ordered parenteral antibiotics. Which of the following actions is done immediately before the antibiotic is started?
- A. The admission orders are written.
- B. A blood culture is drawn.
- C. A complete blood count with differential is drawn.
- D. The parents arrive.
Correct answer: B
Rationale: Before starting antibiotics, a blood culture should be drawn to identify the causative organism. This step is crucial as antibiotics may interfere with the identification process. Drawing a complete blood count with differential or writing admission orders are important steps in patient care but are not as critical as obtaining a blood culture to guide appropriate antibiotic therapy. The arrival of the parents is not directly related to the immediate action required before starting antibiotics in this scenario.
