NCLEX RN Exam Preview Answers
1. The healthcare professional is preparing to percuss the abdomen of a patient. What characteristic of the underlying tissue does percussion assess?
- A. Turgor
- B. Texture
- C. Density
- D. Consistency
Correct answer: C
Rationale: Percussion is a technique used to assess the density of underlying organs by producing sounds that help determine their location and size. Turgor, texture, and consistency are primarily assessed through palpation, not percussion. Turgor refers to skin elasticity, texture pertains to the feel of the tissue surface, and consistency relates to the firmness or resistance of the tissue.
2. The nurse is preparing to assess a hospitalized patient who is experiencing significant shortness of breath. How should the nurse proceed with the assessment?
- A. Have the patient lie down to obtain an accurate cardiac, respiratory, and abdominal assessment.
- B. Obtain a thorough history and physical assessment from the patient's family member.
- C. Immediately perform a complete history and physical assessment to obtain baseline information.
- D. Examine the body areas relevant to the problem and complete the rest of the assessment after the problem has resolved.
Correct answer: D
Rationale: When assessing a patient experiencing significant shortness of breath, it is crucial to prioritize the evaluation of areas directly related to the problem. Having the patient lie down may exacerbate the breathing difficulty. Therefore, the nurse should focus on examining the body areas pertinent to the issue, such as the respiratory and cardiac systems. Completing the rest of the assessment can be deferred until after addressing the immediate problem. Obtaining a complete history or involving family members should come after addressing the acute issue to ensure the patient's safety and comfort.
3. A nursing care plan states, 'Assist the patient to the bedside commode PRN.' When will this patient get this assistance to the commode?
- A. Whenever needed
- B. At bedtime
- C. During the night
- D. During the day
Correct answer: A
Rationale: The correct answer is 'Whenever needed.' The abbreviation 'PRN' stands for 'pro re nata,' which translates to 'as needed' or 'whenever necessary.' This means that the patient will receive assistance to the commode whenever they require it, based on their individual needs and condition. Choices B, C, and D are incorrect because 'PRN' does not specify a specific time like bedtime, during the night, or during the day; instead, it indicates assistance based on the patient's needs.
4. 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.
5. Which of the following is the most likely cause of constipation in a client?
- A. Postponing bowel movement when the urge to defecate occurs
- B. Intestinal infection
- C. Antibiotic use
- D. Food allergies
Correct answer: A
Rationale: The correct answer is to postpone bowel movement when the urge to defecate occurs. Clients who delay bowel movements by ignoring the urge to defecate or not evacuating promptly, such as in situations where they are not near a bathroom, are at higher risk of developing constipation. This behavior leads to a decrease in bowel movement frequency, slowed intestinal motility, and increased fecal water absorption, resulting in hard, dry stools that are difficult to pass. Intestinal infection (choice B), antibiotic use (choice C), and food allergies (choice D) are less likely to be direct causes of constipation compared to postponing bowel movements.
