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. What question must the nurse ask when formulating a nursing diagnosis?

A. What diagnosis did the physician make for this client?
B. What is the issue that I can solve for this client?
C. What physician orders will resolve this issue?
D. What underlying disease does this client have?

Correct answer: B

Rationale: When formulating a nursing diagnosis, the nurse should focus on identifying the client's specific health problems that can be addressed through nursing interventions. The correct answer emphasizes the nurse's role in identifying and addressing client-specific issues through nursing care. Choice A is incorrect because nursing diagnoses are distinct from medical diagnoses made by physicians. Choice C is incorrect as it focuses on physician orders rather than the nurse's role in diagnosing and addressing client problems. Choice D is incorrect because it pertains to identifying underlying diseases, which is not the primary focus of nursing diagnoses.

3. Which of the following is an example of intrapersonal conflict?

A. A nurse feels guilty when she administers essential medication that causes a client to have nausea and vomiting
B. A nurse is called to testify in court about a client she cared for three years ago
C. A nurse feels guilty for working overtime
D. A nurse faces a conflict with a colleague over patient care decisions

Correct answer: A

Rationale: Intrapersonal conflict involves negative feelings or frustrations within oneself. It may be related to decisions or actions that clash with personal morals or beliefs. Choice A is the correct answer because the nurse is experiencing guilt due to administering medication that causes a client to have negative side effects, which reflects an internal struggle. Choices B, C, and D do not represent intrapersonal conflict. Choice B involves a legal obligation, Choice C is related to external factors like working overtime, and Choice D pertains to a conflict with a colleague.

4. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?

A. The Programmed Longevity Theory
B. The Immunological Theory of Aging
C. The Endocrine Theory
D. The Rate of Living Theory

Correct answer: B

Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.

5. A nurse is caring for a 3-day old infant who needs an exchange transfusion. Which of the following statements is appropriate for teaching the child's parents about this procedure?

A. The registered nurse will be performing the procedure
B. The procedure takes approximately 1 ? hours.
C. The nurse will draw out 250cc of blood and then immediately replace it with 250cc
D. The infant will continue to receive phototherapy during the procedure.

Correct answer: B

Rationale: : An exchange transfusion is a method of controlling high bilirubin levels in infants when traditional phototherapy is unsuccessful. During an exchange transfusion, the physician removes 5-10 cc of blood and then replaces it with donor blood. The parents of this infant should know that the procedure is always performed by a physician and will take approximately 1 � hours to complete.
