NCLEX RN Predictor Exam
1. The Sinoatrial Node (SA) is located within which of the following heart structures?
- A. Mitral Valve
- B. Right Ventricle
- C. Right Atrium
- D. Left Atrium
Correct answer: C
Rationale: The Sinoatrial (SA) Node, often called the heart's natural pacemaker, is situated within the upper wall of the Right Atrium. It initiates the electrical impulses that regulate the heartbeat. Choices A, B, and D are incorrect because the SA node is not located in the Mitral Valve, Right Ventricle, or Left Atrium. It is specifically positioned in the Right Atrium to coordinate the heart's rhythm and timing.
2. Which of the following is recommended by Joint Commission guidelines regarding the use of restraints?
- A. Vest restraints should be used because they are the least restrictive type.
- B. Restraints should be used for 48 hours in non-psychiatric patients.
- C. Restraints should be applied to prevent wandering behavior.
- D. Alternative measures must be attempted first.
Correct answer: D
Rationale: When considering the use of restraints, Joint Commission guidelines emphasize the importance of attempting alternative measures before resorting to restraint application. This ensures that a comprehensive assessment is conducted and less restrictive interventions are explored. Using restraints solely based on their perceived level of restrictiveness, as stated in choice A, is not in line with the recommended approach. Restraints should not be used to manage wandering behavior, as indicated in choice C. Additionally, the statement in choice B regarding the duration of restraint use is inaccurate, as restraints on non-psychiatric patients should not exceed 24 hours according to The Joint Commission.
3. For a patient with cirrhosis, which of the following nursing actions can the registered nurse (RN) delegate to unlicensed assistive personnel (UAP)?
- A. Assessing the patient for jaundice
- B. Providing oral hygiene after a meal
- C. Palpating the abdomen for distention
- D. Assisting the patient to choose the diet
Correct answer: B
Rationale: Providing oral hygiene after a meal is an appropriate task to delegate to unlicensed assistive personnel (UAP) as it falls within their scope of practice. UAP can assist with basic personal care activities like oral hygiene. Assessing the patient for jaundice and palpating the abdomen for distention involve making clinical assessments that require a higher level of education and training, typically performed by licensed practical/vocational nurses (LPNs/LVNs) or registered nurses (RNs). Assisting the patient to choose the diet also requires specialized knowledge and would be more appropriate for a nurse to address, considering the complexity of dietary requirements in cirrhosis.
4. When auscultating the blood pressure of a 25-year-old patient, the nurse notices that the phase I Korotkoff sounds begin at 200 mm Hg. At 100 mm Hg, the Korotkoff sounds muffle. At 92 mm Hg, the Korotkoff sounds disappear. How should the nurse record this patient's blood pressure?
- A. 200/92
- B. 200/100
- C. 100/200/92
- D. 200/100/92
Correct answer: A
Rationale: When auscultating blood pressure, it is crucial to note the points at which Korotkoff sounds change. In adults, the last audible sound indicates the diastolic pressure. In this case, the Korotkoff sounds muffle at 100 mm Hg and disappear at 92 mm Hg. Therefore, the blood pressure should be recorded as systolic/diastolic, which is 200/92. Choices B, C, and D are incorrect because they do not reflect the correct points where the Korotkoff sounds change during blood pressure measurement.
5. A nurse caring for a client diagnosed with pertussis is ordered to maintain droplet precautions. Which of the following actions of the nurse upholds droplet precautions?
- A. Assign the client to stay in a negative-pressure room
- B. Use sterilized equipment when sharing between this client and another person with pertussis
- C. Wear a mask if coming within 3 feet of the client
- D. Both A and C
Correct answer: C
Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.
