Nursing Elites

1. When counting a client's radial pulse, the nurse notes the pulse is weak and irregular. To record the most accurate heart rate, what should the nurse do?

• A. Recheck the radial pulse in thirty minutes
• B. Palpate the radial pulse for thirty seconds and double the rate
• C. Count the apical pulse rate for sixty seconds
• D. Compare the radial pulse rate bilaterally and record the higher rate

Correct answer: C

Rationale: The correct answer is to count the apical pulse rate for sixty seconds. The apical pulse is more accurate, especially when peripheral pulses are weak or irregular. Counting the apical pulse for a full minute provides a more precise heart rate measurement. Option A is incorrect because waiting for thirty minutes is unnecessary and could delay potential interventions. Option B is incorrect because doubling the radial pulse rate may not provide an accurate representation of the heart rate. Option D is incorrect because comparing radial pulses bilaterally does not give the most accurate heart rate measurement; the apical pulse is preferred in this situation.

2. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

3. After placing a client at 26-weeks gestation in the lithotomy position, the client complains of dizziness and becomes pale and diaphoretic. What action should the nurse implement?

• A. Instruct the client to take deep breaths.
• B. Place a wedge under the client's hip.
• C. Place the client in the Trendelenburg position.
• D. Remove the client's legs from the stirrups.

Correct answer: B

Rationale: Placing a wedge under the client's hip is the correct action in this scenario. This helps relieve the pressure on the vena cava, which can become compressed in the lithotomy position during pregnancy, improving circulation and reducing symptoms like dizziness and pallor. Instructing the client to take deep breaths (Choice A) may not address the underlying cause of the symptoms. Placing the client in the Trendelenburg position (Choice C) would worsen the situation by further compressing the vena cava. Removing the client's legs from the stirrups (Choice D) may provide temporary relief but does not address the root cause of the issue.

4. A client with type 1 diabetes mellitus is learning to administer insulin. What is the best site for the nurse to recommend for insulin injection?

• A. Abdomen
• B. Thigh
• C. Upper arm
• D. Buttock

Correct answer: A

Rationale: The correct answer is the abdomen. The abdomen is the recommended site for insulin injection due to its faster absorption rate compared to other sites. Insulin injected into the abdomen is absorbed more quickly, leading to better glycemic control. The thigh and upper arm are also common sites for insulin injection, but they have slower absorption rates than the abdomen. The buttock is not a preferred site for insulin injection due to inconsistent absorption and potential risk of injecting into muscle instead of fatty tissue.

5. The nurse is caring for a client with a history of seizure disorder who is receiving phenytoin (Dilantin). Which laboratory value is most important to monitor?

• A. Phenytoin level
• B. Sodium level
• C. Hemoglobin level
• D. White blood cell count

Correct answer: A

Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.
