A nurse is teaching a client with Addison's disease about its cause. What should the nurse say?
- A. It is caused by the overproduction of growth hormone.
- B. It is caused by the lack of production of aldosterone by the adrenal gland.
- C. It is caused by excess thyroid hormone.
- D. It is caused by overactive adrenal glands.
Correct Answer: B
Rationale: The correct answer is B: Addison's disease is caused by the lack of production of aldosterone by the adrenal gland. Aldosterone is a hormone produced by the adrenal glands that helps regulate blood pressure and electrolyte balance in the body. In Addison's disease, the adrenal glands do not produce enough aldosterone, leading to symptoms like low blood pressure, weakness, and electrolyte imbalances. Choice A is incorrect because Addison's disease is not caused by the overproduction of growth hormone. Choice C is incorrect as it mentions excess thyroid hormone, which is not related to Addison's disease. Choice D is incorrect because Addison's disease is characterized by underactive, not overactive, adrenal glands.

A nurse is preparing to initiate a transfusion of packed RBC for a client who has anemia. Which of the following actions should the nurse take?
- A. Check the client's vital signs every 15 min during the transfusion.
- B. Obtain a blood pressure reading every 30 minutes during the transfusion.
- C. Start the transfusion at a rapid rate to improve hemoglobin levels.
- D. Check the client's vital signs every hour during the transfusion.
Correct Answer: A
Rationale: The correct answer is A: Check the client's vital signs every 15 min during the transfusion. This is crucial to monitor for any signs of transfusion reaction, such as fever, chills, or hypotension. Vital signs should be closely monitored initially and then at regular intervals to ensure the client's safety. Checking every 15 minutes allows for early detection and prompt intervention if any adverse reactions occur.
Choice B is incorrect because obtaining a blood pressure reading every 30 minutes is not as frequent as checking vital signs every 15 minutes, which is necessary for early detection of adverse reactions.
Choice C is incorrect as starting the transfusion at a rapid rate can lead to adverse reactions like fluid overload or hemolysis. Transfusions should be started at a slow rate to minimize these risks.
Choice D is incorrect because checking vital signs every hour is not frequent enough to detect early signs of transfusion reactions. Regular monitoring every 15 minutes is recommended for safety.
A staff nurse is teaching a client who has Addison's disease about the disease process. The client asks the nurse what causes Addison's disease. Which of the following responses should the nurse make?
- A. It is caused by the lack of production of aldosterone by the adrenal gland.
- B. It is caused by a viral infection.
- C. It is caused by the overproduction of cortisol.
- D. It is caused by an autoimmune disorder.
Correct Answer: A
Rationale: Correct Answer: A
Rationale:
1. Addison's disease is characterized by adrenal insufficiency.
2. Aldosterone is a hormone produced by the adrenal gland that helps regulate blood pressure and electrolyte balance.
3. Lack of aldosterone production in Addison's disease leads to electrolyte imbalances and low blood pressure.
4. Therefore, the correct answer is A as the lack of aldosterone production by the adrenal gland is the primary cause of Addison's disease.
Summary of other choices:
B. Addison's disease is not caused by a viral infection, so this choice is incorrect.
C. Addison's disease is not caused by the overproduction of cortisol, as it is associated with cortisol deficiency.
D. The most common cause of Addison's disease is an autoimmune disorder where the body attacks the adrenal glands, leading to their dysfunction.
A nurse is caring for a client who has a new diagnosis of essential hypertension. The nurse should monitor the client for which of the following findings that is consistent with this diagnosis?
- A. Vertigo
- B. Fatigue
- C. Excessive thirst
- D. Frequent urination
Correct Answer: A
Rationale: The correct answer is A: Vertigo. Essential hypertension can cause vertigo due to increased pressure in the blood vessels supplying the inner ear. Vertigo is a common symptom of hypertension. Fatigue (B) is a non-specific symptom seen in many conditions. Excessive thirst (C) and frequent urination (D) are more indicative of diabetes mellitus rather than essential hypertension.
A nurse is caring for a client who has a postoperative ileus and an NG tube that has drained 2,500 mL in the past 6 hr. Which of the following electrolyte imbalances should the nurse monitor the client for?
- A. Decreased potassium level
- B. Increased sodium level
- C. Increased calcium level
- D. Decreased magnesium level
Correct Answer: A
Rationale: The correct answer is A: Decreased potassium level. Postoperative ileus can lead to gastrointestinal fluid losses, causing a decrease in potassium levels due to excessive drainage through the NG tube. Potassium is an important electrolyte for maintaining normal muscle function, including the heart. Monitoring potassium levels is essential to prevent complications such as cardiac arrhythmias.
Incorrect choices:
B: Increased sodium level - Unlikely in this scenario as excessive drainage would lead to fluid and electrolyte loss.
C: Increased calcium level - Unrelated to postoperative ileus and NG tube drainage.
D: Decreased magnesium level - Possible but not as critical as monitoring potassium levels in this situation.
A nurse is caring for a client with a tracheostomy. The client's partner has been taught to perform suctioning. Which of the following actions by the partner should indicate to the nurse a readiness for the client's discharge?
- A. Performing the procedure independently
- B. Preparing the suction equipment but needing assistance
- C. Demonstrating knowledge of the tracheostomy care instructions
- D. Asking for assistance with the suctioning procedure
Correct Answer: A
Rationale: The correct answer is A. Performing the procedure independently indicates readiness for discharge as it shows the partner has mastered the skill and can provide proper care without supervision. Choice B indicates the partner still needs assistance, choice C shows knowledge but not necessarily competency, and choice D suggests continued reliance on the nurse.
