Health Promotion and Maintenance NCLEX RN Questions

1. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?

A. Ensure that the client does not need surgery
B. Assess the client's grip strength
C. Perform an Allen test
D. Check a serum potassium level

Correct answer: C

Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.

2. Richard is a 72-year-old with stage 4 lung cancer who has been admitted to the hospital for pneumonia. He is alert and oriented and states he would like to sign a do not resuscitate (DNR) order. His wife enters the room after he has signed it and is very upset that he has made this decision without discussing it with her. She wants to know what she can do to get the DNR reversed. What should your first response be?

A. Contact the unit manager to talk with her
B. Contact the hospital's attorney to discuss with her
C. Try to talk Richard out of his decision
D. Offer caring support for both parties

Correct answer: D

Rationale: The correct response in this situation is to offer caring support for both parties. Richard, being alert and oriented, has the right to make his own decisions, including signing a do not resuscitate (DNR) order. It is important to respect his autonomy while also acknowledging his wife's feelings. By offering caring support, the nurse can facilitate a discussion between Richard and his wife, helping them navigate their emotions and decisions. Contacting the unit manager or hospital's attorney would not be appropriate as the initial response. These actions may escalate the situation and are not focused on addressing the emotional needs of the couple. Trying to talk Richard out of his decision would disregard his autonomy and right to make choices about his own care, which goes against ethical principles of patient autonomy and informed decision-making.

3. When teaching a client with coronary artery disease about nutrition, what should the nurse emphasize?

A. Eating three balanced meals a day
B. Adding complex carbohydrates
C. Avoiding very heavy meals
D. Limiting sodium intake to 7 g per day

Correct answer: C

Rationale: The correct answer is to emphasize avoiding very heavy meals. Eating large, heavy meals can divert blood away from the heart for digestion, potentially endangering clients with coronary artery disease. This practice may lead to an increased risk of plaque accumulation in the arteries, potentially obstructing the delivery of blood and oxygen to vital organs. Choices A, B, and D are incorrect. While eating three balanced meals a day, adding complex carbohydrates, and limiting sodium intake are generally good dietary practices, they are not the primary focus when teaching a client with coronary artery disease about nutrition. The emphasis should be on avoiding heavy meals that can strain the cardiovascular system.

4. What does the 'B' in the SBAR acronym stand for?

A. Background
B. Basic
C. Beginning
D. Break

Correct answer: A

Rationale: The 'B' in the SBAR acronym stands for Background. SBAR is a standardized communication tool used in healthcare to effectively communicate critical information. In this context, 'Background' refers to providing relevant information about the patient's history, current status, and any other pertinent details. This information helps ensure clear and concise communication between healthcare providers, enhancing patient care. Choice B, 'Basic,' is incorrect as the 'B' specifically emphasizes the detailed background information. Choices C and D, 'Beginning' and 'Break,' are not accurate in the context of the SBAR communication tool.

5. After Brandon is stabilized following his second myocardial infarction due to cocaine use, what collaborative process should begin to connect him with additional resources?

A. Law enforcement for further prevention
B. Social services for rehab
C. Narcotics Anonymous
D. Financial counselor to apply for assistance

Correct answer: B

Rationale: Following stabilization, it is essential to connect Brandon with additional resources to address his addiction. Social services are a crucial collaborative partner in this situation because they have access to community resources that can support Brandon's rehabilitation needs. While law enforcement may be involved in certain situations, their primary role is not to provide rehabilitation services. Narcotics Anonymous is a valuable support group but does not offer the comprehensive services that social services for rehab can provide. A financial counselor may be beneficial for addressing financial concerns, but the priority at this stage is to address Brandon's addiction through appropriate rehabilitation services.
