1. Which of the following descriptions best describes the function of the thyroid gland?
- A. The thyroid gland converts glucose into glycogen
- B. The thyroid gland secretes cortisol during times of stress
- C. The thyroid gland regulates body metabolism
- D. The thyroid gland affects skin pigmentation
Correct answer: C
Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.
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. One major difference between long term care and respite centers is the fact that long term care facilities:
- A. provide both physical and emotional care on an ongoing basis, while respite centers offer only temporary services.
- B. provide care for residents on a long-term basis, while respite centers offer only outpatient services.
- C. provide care for residents on a long-term basis, while respite centers offer only temporary services.
- D. There is no difference. Long-term care and respite care are the same.
Correct answer: C
Rationale: The major difference between long-term care and respite centers is that long-term care facilities provide both physical and emotional care on an ongoing, long-term basis. This continuous care is essential for residents who require extended assistance. In contrast, respite centers offer temporary services, providing similar care but for a short-term duration. These short-term services are designed to give family caregivers a break from their daily responsibilities. Choice A is incorrect because both long-term care and respite centers can offer both physical and emotional care, but the key distinction lies in the duration of care provided. Choice B is incorrect as respite centers do not typically offer outpatient services, and the focus is on temporary relief rather than long-term care. Choice D is incorrect as the question clearly highlights a major difference between long-term care and respite centers.
4. A nurse caring for a client diagnosed with pertussis is ordered to maintain droplet precautions. Which of the following actions of the nurse upholds droplet precautions?
- A. Assign the client to stay in a negative-pressure room
- B. Use sterilized equipment when sharing between this client and another person with pertussis
- C. Wear a mask if coming within 3 feet of the client
- D. Both A and C
Correct answer: C
Rationale: When caring for a client requiring droplet precautions, it is essential for the nurse to wear a mask when within 3 feet of the client. This practice helps prevent the transmission of droplet particles that may be produced when the client coughs or sneezes. Assigning the client to a negative-pressure room is not typically necessary for droplet precautions unless specifically indicated for airborne precautions. Using sterilized equipment when sharing between clients with pertussis is important for infection control but does not directly relate to droplet precautions. Therefore, the correct action to uphold droplet precautions in this scenario is to wear a mask when coming within close proximity to the client.
5. The nurse is assessing the vital signs of a 3-year-old patient who appears to have an irregular respiratory pattern. How would the nurse assess this child's respirations?
- A. Respirations should be counted for 1 full minute.
- B. Child's pulse and respirations should be simultaneously checked for 30 seconds and then multiplied by 2.
- C. Child's respirations should be checked for a minimum of 5 minutes to identify any variations in his or her respiratory pattern.
- D. Patient's respirations should be counted for 15 seconds and then multiplied by 4.
Correct answer: A
Rationale: To accurately assess a child's respiratory pattern, the nurse should count respirations for a full minute. This duration provides a comprehensive view of the child's breathing pattern, ensuring abnormalities are not missed. Counting for only 30 seconds may not capture irregularities effectively. Checking respirations for 5 minutes is excessive and unnecessary for a routine assessment. Counting for 15 seconds and multiplying by 4 is not as precise as a full-minute count. Pulse and respirations should not be checked simultaneously; instead, the nurse should count respirations unobtrusively while appearing to take the child's pulse. Therefore, the correct approach is to count the child's respirations for 1 full minute to obtain an accurate assessment.
