Nursing Elites

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. When a mother is inquiring about her child's ability to potty train, what is the most critical aspect of toilet training?

• A. The age of the child
• B. The child's ability to understand instructions
• C. The overall mental and physical abilities of the child
• D. Consistent attempts with positive reinforcement

Correct answer: C

Rationale: The most critical aspect of toilet training is the overall mental and physical abilities of the child. While age can play a role, it is not the sole determining factor. Understanding instructions is important but may not be the most critical aspect. Consistent attempts with positive reinforcement can be helpful, but without considering the child's abilities, it may not lead to successful potty training.

3. What is involved in obtaining informed consent?

• A. An explanation of the reasons for the procedure
• B. A signature on a form indicating the client agrees to the procedure
• C. A statement affirming liability if complications arise during the procedure
• D. Both A and C

Correct answer: A

Rationale: Informed consent involves providing the client with an explanation of the reasons for the procedure, the potential risks, benefits, and available alternatives. It is essential for the healthcare provider to ensure that the client understands the information provided before agreeing to the procedure. While obtaining a signature on a consent form is part of the process, it is not the sole indicator of informed consent. Option C, which mentions liability statements, is incorrect as informed consent focuses on ensuring the client understands the procedure, not on affirming liability. Therefore, the correct answer is the explanation of the reasons for the procedure.

4. Which of the following conditions may warrant a serum creatinine level?

• A. Rhabdomyolysis
• B. Digitalis toxicity
• C. Glomerulonephritis
• D. All answers are correct

Correct answer: D

Rationale: A serum creatinine level may be warranted in conditions that can affect renal function or cause muscle breakdown. Rhabdomyolysis, characterized by muscle injury and breakdown, can lead to elevated creatinine levels due to the release of creatinine from muscles. Digitalis toxicity can impair renal function, leading to a need for monitoring creatinine levels. Glomerulonephritis, an inflammatory condition affecting the kidney's filtering units, can also impact renal function and require assessment of creatinine levels. Therefore, all the provided conditions may warrant a serum creatinine level to assess renal function and muscle breakdown.

5. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.
