Exam Cram NCLEX RN Practice Questions
1. The nurse is assessing children in a pediatric clinic. Which statement is true regarding the measurement of blood pressure in children?
- A. Blood pressure guidelines for children are based on age.
- B. Phase II Korotkoff sounds are the best indicator of systolic blood pressure in children.
- C. Using a Doppler device is recommended for accurate blood pressure measurements until adolescence.
- D. The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children.
Correct answer: D
Rationale: The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults. Blood pressure guidelines for children are based on more than just age, but also sex and height. Phase I Korotkoff, not Phase II, is the best indicator of systolic blood pressure. The true statement regarding the measurement of blood pressure in children is that the disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults.
2. When placing a patient in the AP position for an X-ray, what position would the patient be in?
- A. Facing the X-ray film.
- B. Right side against the X-ray film.
- C. Left side against the X-ray film.
- D. Facing away from the X-ray film
Correct answer: D
Rationale: The AP position stands for Anteroposterior Projection. When a patient is in the AP position for an X-ray, they are facing away from the X-ray film. This positioning allows for a clear view of the structures being imaged from front to back. Choices A, B, and C are incorrect because the patient is not facing or positioned against the X-ray film in the AP position, but rather facing away from it to capture the necessary diagnostic information.
3. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?
- A. Alert the physician immediately as this is a sign of impending cardiac arrest.
- B. Check to see that all leads are attached and rerun the EKG.
- C. Increase the sensitivity control to 20 mm deflection.
- D. Decrease the run speed to 50.
Correct answer: C
Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
4. A client is post-op day #1 after a hemilaminectomy. The nurse removes the dressing as ordered and notes that the incision appears slightly red, with a small amount of serous drainage coming from the site. The edges of the incision are approximated. What is the next action of the nurse?
- A. Assist the client to shower as ordered and monitor the site for further changes
- B. Instruct the client to lie prone to allow the site to dry
- C. Place antibiotic ointment and a sterile dressing over the site
- D. Notify the physician for an antibiotic order
Correct answer: A
Rationale: An incision that appears slightly red with a small amount of serous drainage on the first day following surgery is going through a normal healing process. It is important to keep the incision clean. In this case, the nurse should assist the client to shower as ordered to maintain hygiene and monitor for changes in the incision site. Instructing the client to lie prone may not be necessary and could cause discomfort. Applying antibiotic ointment without a specific order is not recommended as it can interfere with the healing process. Notifying the physician for an antibiotic order is premature at this stage since the incision is showing normal signs of healing.
5. Following hospitalization for congestive heart failure, a client is discharged. The nurse teaching the family suggests they encourage the client to rest frequently in which of the following positions?
- A. High Fowler's
- B. Supine
- C. Left lateral
- D. Low Fowler's
Correct answer: A
Rationale: The correct answer is High Fowler's. Sitting in a chair or resting in a bed in the high Fowler's position helps decrease the cardiac workload and facilitates breathing in clients with congestive heart failure. This position helps reduce venous return and increases lung expansion, improving oxygenation. The supine position (choice B) may lead to increased pressure on the heart and lungs, making it less suitable for these clients. The left lateral position (choice C) is not as effective as High Fowler's in reducing cardiac workload and improving breathing. Low Fowler's position (choice D) does not provide the same benefits as the High Fowler's position for clients with congestive heart failure.
