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. When taking blood pressures on a variety of people at a health fair, what should the nurse keep in mind?

A. After menopause, blood pressure readings in women are usually higher than those taken in men.
B. The blood pressure of an African-American adult is usually higher than that of a non-Hispanic White adult of the same age.
C. Blood pressure measurements in people who are overweight are usually higher than those of people who are at a normal weight.
D. A teenager's blood pressure reading may be lower than that of an adult.

Correct answer: B

Rationale: When assessing blood pressures, it is important to consider that the blood pressure of African-American adults is typically higher than that of non-Hispanic White adults of the same age. This is significant as Black individuals in the United States have a higher prevalence of hypertension compared to other groups. Blood pressure readings in women are generally higher than in men after menopause. Additionally, blood pressure measurements in overweight individuals are typically higher than those in individuals of normal weight. While teenagers may have lower blood pressure readings than adults, it is crucial to recognize the trend of a gradual rise in blood pressure throughout childhood and into adulthood. Therefore, the correct choice is B. Choices A, C, and D are incorrect as they do not reflect the typical blood pressure differences observed in various populations.

3. In which of the following ways can a healthcare provider promote the sense of taste for an older adult?

A. Mixing foods together on the dinner tray
B. Avoiding cologne, air fresheners, or room deodorizers
C. Encouraging the client to chew food thoroughly
D. Discouraging the use of salt or seasonings with prepared food

Correct answer: C

Rationale: As individuals age, their sense of taste may diminish, impacting the enjoyment of eating. One effective way for a healthcare provider to promote the sense of taste for an older adult is by encouraging them to chew food thoroughly. Thorough chewing increases the contact of food with the taste buds, enhancing the chances of experiencing the flavors. Mixing foods together on the dinner tray may not necessarily enhance taste perception. Avoiding strong scents like cologne, air fresheners, or room deodorizers is more related to olfactory senses rather than taste. Discouraging the use of salt or seasonings can further diminish the taste experience for older adults who may already have reduced taste sensitivity.

4. The nurse is examining a 2-year-old child and asks, "May I listen to your heart now?"? Which critique of the nurse's technique is most accurate?

A. Asking questions may enhance the child's autonomy.
B. Asking the child for permission helps develop a sense of trust.
C. This question is an inappropriate statement because children at this age like to have choices.
D. Children at this age like to say, "No."? The examiner should not offer a choice when no choice is available.

Correct answer: D

Rationale: Children at the age of 2 often like to assert their independence by saying "No."? In situations where there is actually no choice available, offering a false choice can lead to a lack of trust. It is important not to offer a choice when there isn't one, as doing so may undermine trust. While asking for permission can enhance autonomy and trust, offering a limited option like, "Shall I listen to your heart next or your tummy?"? may be a better approach. Therefore, the correct critique of the nurse's technique in this scenario is that children at this age tend to say "No,"? so the examiner should avoid offering a choice when there isn't a real alternative.

5. When teaching a patient to use the three-point gait technique of crutch use:

A. The injured leg moves ahead at the same time as both crutches.
B. One crutch moves at a time and is then followed by the injured leg.
C. Both crutches move ahead at the same time followed by both legs at the same time.
D. None of the above are correct.

Correct answer: A

Rationale: The correct technique for a three-point gait involves the injured leg moving simultaneously with both crutches, followed by the uninjured leg. This gait pattern is utilized when the patient is unable to bear full weight on one of their legs. Choice A accurately describes the appropriate sequence of movements for the three-point gait technique. Choices B and C do not accurately reflect the correct pattern of movement during the three-point gait technique, making them incorrect. Choice D is incorrect as there is a correct option among the choices provided.
