Nursing Elites

1. The healthcare provider is assessing a client with suspected syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory findings is most consistent with this condition?

• A. Increased serum sodium
• B. Decreased urine specific gravity
• C. Decreased serum osmolality
• D. Increased serum potassium

Correct answer: C

Rationale: The correct answer is C: Decreased serum osmolality. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. The dilution of sodium results in decreased serum osmolality. Option A is incorrect because SIADH causes hyponatremia, resulting in decreased serum sodium levels. Option B is incorrect because SIADH leads to concentrated urine with increased urine specific gravity. Option D is incorrect as SIADH does not typically affect serum potassium levels.

2. A client with terminal pancreatic cancer asks questions about a do not resuscitate order. Which of the following statements should be included in the RN's teaching to the client?

• A. When a heart ceases to beat, the client is pronounced clinically dead.
• B. Physicians must write do not resuscitate (DNR) orders.
• C. A DNR order can be written after the healthcare provider has discussed it with the client and family.
• D. A DNR requires a court decision.

Correct answer: C

Rationale: A DNR order is typically written after the healthcare provider has discussed the implications with the patient and their family. This ensures that the patient and family are fully informed before making such a critical decision. Choice A is incorrect because pronouncing clinical death is a medical determination, not directly related to DNR orders. Choice B is incorrect because while physicians commonly write DNR orders, the discussion with the patient and family is crucial. Choice D is incorrect because a DNR order does not require a court decision; it is a decision made in collaboration with the healthcare team and the patient or family.

3. A client newly diagnosed with DM asks a nurse why it is necessary to monitor blood glucose levels so often. The nurse's best response would be:

• A. It helps to adjust insulin doses more precisely.
• B. It helps to prevent complications of diabetes.
• C. It helps to identify the best diet for you.
• D. It helps to reduce the need for medications.

Correct answer: B

Rationale: Monitoring blood glucose levels frequently is crucial for preventing complications in diabetes. By keeping a close eye on blood glucose levels, healthcare providers can intervene in a timely manner if levels are out of range, thus reducing the risk of long-term complications such as nerve damage, kidney disease, and vision problems. Choices A, C, and D are incorrect because while monitoring blood glucose levels may indirectly contribute to adjusting insulin doses, identifying the best diet, and reducing the need for medications, the primary purpose is to prevent complications through timely interventions.

4. What is the mechanism of action of corticotropin (Acthar) when prescribed as replacement therapy for a male client who has undergone surgical removal of a pituitary tumor?

• A. It decreases cyclic adenosine monophosphate (cAMP) production and affects the metabolic rate of target organs.
• B. It interacts with plasma membrane receptors to inhibit enzymatic actions.
• C. It interacts with plasma membrane receptors to produce enzymatic actions that affect protein, fat, and carbohydrate metabolism.
• D. It regulates the threshold for water reabsorption in the kidneys.

Correct answer: C

Rationale: Corticotropin (ACTH) stimulates the adrenal cortex to secrete cortisol and other hormones, affecting protein, fat, and carbohydrate metabolism. Choice A is incorrect because corticotropin does not decrease cAMP production; instead, it stimulates enzymatic actions. Choice B is incorrect because corticotropin does not inhibit enzymatic actions but rather produces enzymatic actions. Choice D is incorrect because corticotropin's mechanism of action does not involve regulating the threshold for water reabsorption in the kidneys.

5. A client with DM is preparing for a foot care exam. The nurse should advise the client to:

• A. Wear loose-fitting shoes to protect the feet.
• B. Apply lotion to the tops and bottoms of the feet to keep the skin moist.
• C. Avoid using a heating pad to prevent burns on the feet.
• D. Avoid using sharp instruments to trim the toenails.

Correct answer: D

Rationale: The correct answer is to advise the client to avoid using sharp instruments to trim the toenails. This is crucial because using sharp instruments can lead to injuries such as cuts or wounds, increasing the risk of infections, especially in clients with diabetes who have decreased sensation in their feet. Choice A is incorrect because tight shoes can restrict circulation and increase the risk of pressure sores. Choice B is incorrect because applying lotion between the toes can create a moist environment, leading to fungal infections. Choice C is incorrect because using a heating pad can lead to burns, which can go unnoticed due to decreased sensation in diabetic feet.
