Nursing Elites

1. What is the proper technique for measuring a patient's blood pressure?

• A. Place the cuff at heart level and listen for Korotkoff sounds
• B. Ensure the patient is in a seated position and inflate the cuff to 180 mmHg
• C. Use a manual sphygmomanometer and measure blood pressure on both arms
• D. Monitor pulse rate and apply pressure to the brachial artery

Correct answer: A

Rationale: The correct technique for measuring blood pressure involves placing the cuff at heart level to ensure accurate readings. Listening for Korotkoff sounds helps determine the systolic and diastolic pressures. Choice B is incorrect as inflating the cuff to 180 mmHg is excessive and can lead to inaccurate readings. Choice C is incorrect as it is unnecessary to measure blood pressure on both arms unless there is a specific medical reason to do so. Choice D is incorrect as monitoring pulse rate and applying pressure to the brachial artery are not part of the standard blood pressure measurement technique.

2. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

3. During an initial assessment of a client, a nurse notices a discrepancy between the client's current IV infusion and the information received during the shift report. Which of the following actions should the nurse take?

• A. Complete an incident report and place it in the client's medical record.
• B. Compare the current infusion with the prescription in the client's medication record.
• C. Contact the charge nurse to see if the prescription was changed.
• D. Submit a written warning for the nurse involved in the incident.

Correct answer: B

Rationale: The correct action for the nurse to take when noticing a discrepancy between the client's current IV infusion and the information received during the shift report is to compare the current infusion with the prescription in the client's medication record. This step is crucial to ensure the accuracy of the prescribed treatment and to prevent any potential harm to the client. Option A is incorrect because completing an incident report should only be done after verifying the discrepancy. Option C is incorrect as contacting the charge nurse should come after confirming the details. Option D is incorrect as submitting a written warning is not appropriate without verifying the information first.

4. A nurse is caring for a client who is receiving intermittent enteral tube feedings. Which of the following places the client at risk for aspiration?

• A. A history of gastroesophageal reflux disease.
• B. Receiving a formula with high osmolarity.
• C. Sitting in a high-Fowler's position during the feeding.
• D. A residual of 65 mL 1 hour postprandial.

Correct answer: A

Rationale: The correct answer is A: A history of gastroesophageal reflux disease. Clients with gastroesophageal reflux disease have a higher risk of aspiration during tube feeding due to the potential for reflux of stomach contents into the lungs. This increases the risk of aspiration pneumonia. Choices B, C, and D are incorrect. High osmolarity formulas may cause diarrhea but do not directly increase the risk of aspiration. Sitting in a high-Fowler's position actually reduces the risk of aspiration by promoting proper digestion and reducing the chance of regurgitation. A residual of 65 mL 1 hour postprandial is within an acceptable range and does not directly indicate a risk for aspiration.

5. What are the primary differences between left-sided and right-sided heart failure?

• A. Left-sided: Pulmonary congestion; Right-sided: Systemic edema
• B. Right-sided: Pulmonary congestion; Left-sided: Systemic edema
• C. Left-sided: Systemic edema; Right-sided: Pulmonary congestion
• D. Right-sided: Pulmonary congestion; Left-sided: Heart failure

Correct answer: A

Rationale: The correct answer is A: "Left-sided: Pulmonary congestion; Right-sided: Systemic edema." Left-sided heart failure primarily affects the lungs, leading to pulmonary congestion, which manifests as symptoms like shortness of breath and cough. On the other hand, right-sided heart failure causes systemic congestion and edema, often presenting as swelling in the legs and abdomen due to fluid retention. Choice B is incorrect because it swaps the features of left-sided and right-sided heart failure. Choice C is incorrect as it also incorrectly switches the characteristics of the two types of heart failure. Choice D is incorrect because it inaccurately associates left-sided heart failure with pulmonary congestion and right-sided heart failure with heart failure itself, which is not a distinguishing feature.
