Nursing Elites

1. What type of blood pressure measurement error is most likely to occur if the nurse does not check for the presence of an auscultatory gap?

• A. Diastolic blood pressure may not be heard.
• B. Diastolic blood pressure may be falsely low.
• C. Systolic blood pressure may be falsely low.
• D. Systolic blood pressure may be falsely high.

Correct answer: C

Rationale: If an auscultatory gap is undetected, a falsely low systolic reading may occur. This gap can lead to an underestimation of the systolic blood pressure, causing potential misinterpretation of the patient's condition. The diastolic blood pressure may not be heard due to the gap, but the critical issue in this scenario is the risk of underestimating systolic blood pressure, which can impact clinical decision-making. Choices B, C, and D are incorrect because the key concern in this context is the potential for a falsely low systolic blood pressure reading when an auscultatory gap is not assessed.

2. A patient is diagnosed with essential hypertension. Which of the following blood pressures would you expect to see in this patient prior to taking medications for the condition?

• A. 142/92
• B. 118/72
• C. 120/80
• D. 138/88

Correct answer: A

Rationale: Before starting medications for essential hypertension, a patient would typically present with a blood pressure reading equal to or greater than 140/90. This indicates high blood pressure and is characteristic of essential hypertension. Choice A, 142/92, falls within this range, making it the correct answer. Choices B (118/72), C (120/80), and D (138/88) all have blood pressure readings that are within the normal range and would not typically be expected in a patient diagnosed with essential hypertension. Therefore, choices B, C, and D are incorrect as they do not align with the elevated blood pressure levels seen in essential hypertension.

3. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?

• A. Controls stray electrical currents.
• B. Promotes efficient use of electricity.
• C. Shuts off the appliance if there is an electrical surge.
• D. Divides the electricity among the appliances in the room.

Correct answer: A

Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.

4. Which technique is correct when assessing the radial pulse of a patient?

• A. Palpate for 1 minute if the rhythm is irregular.
• B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
• C. Palpate for 2 full minutes to detect any variation in amplitude.
• D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.

Correct answer: A

Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.

5. In addition to standard precautions, the nurse caring for a patient with rubella would plan to implement what type of precautions?

• A. Droplet precautions
• B. Airborne precautions
• C. Contact precautions
• D. Universal precautions

Correct answer: A

Rationale: Rubella is an illness transmitted by large-particle droplets, so the nurse should implement droplet precautions in addition to standard precautions. Airborne precautions are used for diseases spread through small particles in the air, such as tuberculosis, varicella, and rubeola. Contact precautions are utilized for diseases transmitted by direct contact with the patient or their environment. Universal precautions and body substance isolations are part of the CDC's standard precautions recommendations, but do not specifically address the transmission route of rubella.
