Exam Cram NCLEX RN Practice Questions
1. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?
- A. 10
- B. 70
- C. 80
- D. 100
Correct answer: B
Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.
2. When providing mouth care to a patient in a coma, what should you do to provide good and safe mouth care?
- A. keep the head of the bed up to prevent aspiration
- B. brush the teeth and rinse the mouth with a cup of water
- C. use a special foam swab to brush only the tongue
- D. use a special foam swab to brush the tongue and teeth
Correct answer: D
Rationale: When providing mouth care to a patient in a coma, it is crucial to use a special foam swab to brush the tongue and teeth. This method helps maintain good oral hygiene for comatose patients. Special foam swabs are designed to effectively clean all areas of the mouth, including the cheeks and tongue, ensuring thorough care. Using water for mouth care in comatose patients can lead to aspiration, so it is important to avoid this practice. Keeping the head of the bed up alone does not prevent aspiration during mouth care for comatose patients, making choice A incorrect. Merely brushing the tongue (choice C) or using a foam swab only on the tongue (choice B) may not provide the comprehensive mouth care necessary for patients in a coma.
3. Which of the following is a disadvantage of using a dry heat application?
- A. Dry heat is more likely to cause burns than moist heat
- B. Dry heat does not penetrate deeply into the tissues
- C. Dry heat causes the skin to dry out more quickly
- D. Dry heat can quickly cause skin breakdown
Correct answer: C
Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.
4. What is a common error when taking a pulse?
- A. Placing the index finger on the radial artery located on the thumb side of a patient's wrist.
- B. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure.
- C. Counting the pulse for 15 seconds and multiplying the number by four.
- D. None of the above will cause errors.
Correct answer: C
Rationale: The correct answer is counting the pulse for 15 seconds and multiplying the number by four. To accurately assess a patient's heart rate or pulse, it is crucial to count the pulse for a full minute. Counting for only 15 seconds and then multiplying by four may result in an inaccurate heart rate calculation. This approach could miss arrhythmias or intermittent pulsations that could be vital indicators of the patient's condition. Placing the index finger on the radial artery, which is located on the thumb side of the patient's wrist, is the correct technique for taking a pulse. Noting a pulse as 'weak' when the pulsation disappears upon adding pressure is a valid observation and not an error in itself. Therefore, the most common error in this scenario is incorrectly calculating the pulse rate by multiplying a 15-second count by four.
5. A second-year nursing student has just suffered a needlestick while working with a patient that is positive for AIDS. Which of the following is the most significant action that the nursing student should take?
- A. Immediately see a social worker
- B. Start prophylactic AZT treatment
- C. Start prophylactic Pentamidine treatment
- D. Seek counseling
Correct answer: B
Rationale: Starting prophylactic AZT treatment is the most critical intervention in this scenario. Azidothymidine (AZT) is an antiretroviral medication used to prevent and treat HIV/AIDS by reducing the replication of the virus. Post-exposure prophylaxis (PEP) for HIV involves taking medication to suppress the virus and prevent infection after exposure. PEP should be initiated within 72 hours of potential HIV exposure to be effective. Seeking treatment quickly is crucial to enhance its effectiveness. Seeing a social worker (Choice A) may be helpful for emotional support but is not the immediate priority. Pentamidine treatment (Choice C) is not indicated for post-exposure prophylaxis for HIV. Seeking counseling (Choice D) is important for the nursing student's emotional well-being but does not address the urgent need for post-exposure prophylaxis to prevent HIV transmission.
