1. What is the function of aldosterone?
- A. Regulates body temperature.
- B. Decreases blood pressure.
- C. Increases sodium reabsorption.
- D. Promotes water excretion.
Correct answer: C
Rationale: Aldosterone increases the reabsorption of sodium in the kidneys, which leads to an increase in blood volume and blood pressure. Choice A is incorrect as aldosterone does not regulate body temperature. Choice B is incorrect as aldosterone increases blood pressure by increasing sodium reabsorption. Choice D is incorrect as aldosterone promotes water retention by increasing sodium reabsorption.
2. How should a healthcare provider care for a patient with a tracheostomy?
- A. Clean the tracheostomy site daily
- B. Change the tracheostomy ties daily
- C. Suction the tracheostomy regularly
- D. Provide humidified oxygen
Correct answer: C
Rationale: Suctioning the tracheostomy regularly is crucial in caring for a patient with a tracheostomy as it helps keep the airway clear of secretions, preventing blockages and potential complications. Cleaning the tracheostomy site daily is important for hygiene but not as critical as regular suctioning. Changing the tracheostomy ties daily may not be necessary unless soiled or loose. Providing humidified oxygen may be part of the care plan but is not as directly related to maintaining the tracheostomy patency as suctioning.
3. A client is reviewing information about advance directives with a newly admitted client. Which statement by the client indicates understanding?
- A. I can change my living will whenever I want.
- B. I do not need a living will if I have a durable power of attorney.
- C. My family will make decisions for me if I am unable to.
- D. I need a living will only if I am seriously ill.
Correct answer: A
Rationale: The correct answer is A because the client understanding that they can change their living will whenever they want shows comprehension of advance directives. Choices B, C, and D are incorrect: B is inaccurate as both documents serve different purposes; C may not always be the case based on the client's wishes and legal documents; D is incorrect because a living will is not only for serious illness but also for end-of-life care decisions.
4. Are kidneys part of the lymphatic system?
- A. True
- B. False
- C. Not Sure
- D. None of the above
Correct answer: False
Rationale: The correct answer is False. Kidneys are not part of the lymphatic system; they are part of the urinary system. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. Therefore, choices A, C, and D are incorrect because kidneys are not associated with the lymphatic system.
5. The nurse is instructing the 35 year old client to perform a testicular self-examination. The nurse tells the client:
- A. To examine the testicles while lying down
- B. That the best time for the examination is after a shower
- C. To gently feel the testicle with one finger to feel for a growth
- D. That testicular self-examination should be done at least every 6 months
Correct answer: B
Rationale: The best time to perform a testicular self-examination (TSE) is after a warm shower or bath. The heat from the water relaxes the scrotal skin, making it easier to feel any abnormalities, lumps, or changes in the testicles. This relaxation allows for a more thorough and accurate examination.
