1. What is the primary route of transmission of MRSA?

• A. Shared needles
• B. Hands of healthcare workers
• C. Items in the healthcare environment
• D. Blood transfusions

Correct answer: B

Rationale: The correct answer is 'Hands of healthcare workers.' MRSA is primarily transmitted via the unwashed hands of healthcare workers who can carry the Staphylococcus aureus bacterium from one patient to another. Shared needles, items in the healthcare environment, and blood transfusions are not the main routes of transmission for MRSA. Shared needles can transmit bloodborne pathogens, items in the healthcare environment can harbor bacteria but are not the primary mode for MRSA, and blood transfusions are not a common route for MRSA transmission.

2. Which of the following is a disadvantage of using a dry heat application?

• A. Dry heat is more likely to cause burns than moist heat
• B. Dry heat does not penetrate deeply into the tissues
• C. Dry heat causes the skin to dry out more quickly
• D. Dry heat can quickly cause skin breakdown

Correct answer: C

Rationale: The correct answer is that dry heat causes the skin to dry out more quickly. When comparing dry and moist heat applications, dry heat is less likely to cause burns and skin breakdown. However, one of the disadvantages of dry heat is that it does not penetrate deeply into the tissues and may lead to faster drying out of the skin. This can have negative effects on skin integrity and overall comfort during therapy. Choice A is incorrect because dry heat is less likely to cause burns than moist heat. Choice B is incorrect as dry heat may not penetrate deeply into tissues. Choice D is incorrect as dry heat is less likely to cause skin breakdown compared to moist heat.

3. 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.

4. The most accurate reading for a temperature is done:

• A. Orally
• B. Aurally through a clean canal
• C. Rectally
• D. Axially

Correct answer: B

Rationale: Aural readings are done through the ear canal. The tympanic membrane shares a blood supply with the hypothalamus, the brain area that regulates body temperature. Taking the temperature aurally through a clean canal ensures an accurate reading. Choice A (Orally) is not the most accurate method for temperature measurement as it can be affected by external factors like drinking hot or cold liquids. Choice C (Rectally) is invasive and less practical for routine temperature monitoring. Choice D (Axially) is not a standard method for temperature measurement and may not provide accurate results.

5. A physician's order instructs a nurse to take a temperature at the axilla. Where would the nurse place the thermometer?

• A. In the rectum
• B. In the mouth
• C. On the temples
• D. In the armpit

Correct answer: A

Rationale: When a physician's order specifies taking a temperature at the axilla, the nurse should place the thermometer in the armpit. The axilla is the anatomical area of the armpit located under the arms, proximal to the trunk. Placing the thermometer in the rectum (Choice A) is used for rectal temperature measurements, in the mouth (Choice B) for oral temperature measurements, and on the temples (Choice C) is not a common site for temperature assessment. Therefore, the correct placement based on the given instruction is in the armpit.
