1. 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.

2. Which of the following medical terms means 'surgical fixation of the stomach'?

A. Abdominorrhaphy
B. Gastroplasty
C. Gastropexy
D. Abdominorrhexis

Correct answer: C

Rationale: The correct answer is 'Gastropexy,' which means 'surgical fixation of the stomach.' This procedure involves surgically fixing the stomach in place. 'Abdominorrhaphy' refers to suturing or repairing the abdomen, not related to fixing the stomach. 'Gastroplasty' is a surgical reconstruction of the abdomen, not specifically related to fixing the stomach. 'Abdominorrhexis' refers to the rupture or tearing of the abdomen, not a surgical fixation procedure.

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. What does the medical term 'basophilia' refer to?

A. An attachment of the epithelial cells of the skin to a basement membrane
B. An overabundance of a particular white blood cell in the peripheral blood
C. An underrepresentation of basophils on a blood smear
D. None of the above

Correct answer: B

Rationale: The correct answer is 'An overabundance of a particular white blood cell in the peripheral blood.' Basophilia specifically indicates an increased number of basophils in the peripheral blood. It can be observed in conditions like leukemia and certain allergic reactions. Choice A is incorrect as it describes something unrelated to basophilia. Choice C is incorrect as it suggests a decrease in basophils, which is opposite to the actual meaning of basophilia. Choice D is also incorrect as basophilia does have a defined medical significance.

5. A client who complains of nausea and seems anxious is admitted to the nursing unit. The nurse should take which of the following actions regarding completion of the admission interview?

A. Help the client to get settled and conduct the interview the next morning when the client is rested
B. Conduct the interview immediately, directing the majority of the questions to the client
C. Conduct the interview as soon as uninterrupted time is available to address the client's concerns
D. Ask the charge nurse to interview the client while the admitting nurse calls the doctor for anti-nausea and anti-anxiety medication

Correct answer: C

Rationale: When dealing with a client who is experiencing nausea and anxiety, it is important to promptly conduct the admission interview to address their concerns. This allows for the collection of accurate data while attending to the client's immediate needs. Delaying the interview until the next morning (Choice A) may not be in the best interest of the client as timely assessment and intervention are essential. Directing questions to the client's spouse (Choice B) may not provide accurate information from the client themselves. Asking another nurse to conduct the interview while administering medications (Choice D) does not prioritize building a therapeutic relationship with the client, which is crucial in addressing their concerns and providing holistic care.
