1. A client has recently started using a behind-the-ear hearing aid. Which of the following statements should the nurse identify as an indication that the client understands the use of this assistive device?
- A. This type of hearing aid allows for fine-tuning of volume.
- B. I should ensure the hearing aid stays secure during exercise.
- C. I might hear a whistling sound when I first insert the hearing aid.
- D. I will be sure to remove my hearing aid before taking a shower.
Correct answer: D
Rationale: The correct answer is D because removing the hearing aid before taking a shower is essential to prevent water damage, as moisture can harm the device. Choice A is incorrect because behind-the-ear hearing aids do allow for fine-tuning of volume. Choice B is incorrect because exercise may cause the hearing aid to shift position, so it's important to ensure it stays secure. Choice C is incorrect because hearing a whistling sound when inserting the hearing aid may indicate improper placement or fit.
2. A healthcare professional is preparing to administer enoxaparin subcutaneously to a client. Which of the following actions should the healthcare professional take?
- A. Administer the medication with the needle at a 45-degree angle.
- B. Administer the medication with the needle at a 90-degree angle.
- C. Inject the medication into the muscle.
- D. Pinch the skin before injecting.
Correct answer: B
Rationale: Enoxaparin is a medication that is administered subcutaneously, which means it should be injected into the fatty tissue layer beneath the skin. Administering enoxaparin at a 90-degree angle ensures proper absorption and reduces the risk of injecting the medication into muscle tissue, which could affect its effectiveness. Injecting the medication at a 45-degree angle may lead to improper absorption as it may not reach the subcutaneous tissue adequately. Injecting the medication into the muscle instead of subcutaneously can alter the absorption rate and therapeutic effects. Pinching the skin before injecting is not necessary for administering enoxaparin subcutaneously and may cause unnecessary discomfort to the client.
3. A client who is nonambulatory notifies the nurse that his trash can is on fire. After the nurse confirms the fire, which of the following actions should the nurse take next?
- A. Activate the emergency fire alarm
- B. Extinguish the fire
- C. Evacuate the client
- D. Confine the fire
Correct answer: C
Rationale: The correct action for the nurse to take next, after confirming the fire, is to evacuate the client. In a fire situation, following the RACE mnemonic, the priority is to rescue or evacuate clients to ensure their safety. Activating the emergency fire alarm (Choice A) is important to alert others and the fire department, but evacuating the client takes precedence. Extinguishing the fire (Choice B) may put the nurse and client at risk and is best left to trained personnel. Confining the fire (Choice D) is not the nurse's responsibility; the focus should be on ensuring the client's safety by evacuating them.
4. The nurse is caring for a client diagnosed with hypothyroidism. Which finding should the nurse expect to observe?
- A. Weight gain
- B. Heat intolerance
- C. Increased appetite
- D. Frequent diarrhea
Correct answer: A
Rationale: The correct answer is weight gain. In hypothyroidism, there is a decrease in metabolic rate, which can lead to weight gain. Heat intolerance (choice B) is more commonly associated with hyperthyroidism. Increased appetite (choice C) and frequent diarrhea (choice D) are not typical findings in hypothyroidism. Therefore, choices B, C, and D are incorrect.
5. A healthcare professional is preparing to assess a patient for orthostatic hypotension. Which piece of equipment will the professional obtain to assess for this condition?
- A. Thermometer
- B. Elastic stockings
- C. Blood pressure cuff
- D. Sequential compression devices
Correct answer: C
Rationale: To assess for orthostatic hypotension, a healthcare professional needs to obtain a blood pressure cuff. Orthostatic hypotension is defined as a drop in blood pressure greater than 20 mm Hg in systolic pressure or 10 mm Hg in diastolic pressure when moving from lying down to a standing position. A thermometer (Choice A) is used to measure body temperature and is not directly related to assessing orthostatic hypotension. Elastic stockings (Choice B) are used for preventing deep vein thrombosis and improving circulation in the lower extremities, not for assessing orthostatic hypotension. Sequential compression devices (Choice D) are mechanical pumps that are used to prevent deep vein thrombosis and are not specifically used for assessing orthostatic hypotension.
