Nursing Elites

1. A male client with primary diabetes insipidus is ready for discharge on desmopressin (DDAVP). Which instruction should nurse Lina provide?

• A. Administer desmopressin while the suspension is cold.
• B. Your condition isn't chronic, so you won't need to wear a medical identification bracelet.
• C. You may not be able to use desmopressin nasally if you have nasal discharge or blockage.
• D. You won't need to monitor your fluid intake and output after you start taking desmopressin.

Correct answer: C

Rationale: The correct instruction is choice C: 'You may not be able to use desmopressin nasally if you have nasal discharge or blockage.' Nasal congestion or blockage can interfere with the absorption of nasally administered desmopressin. Choices A, B, and D are incorrect. Choice A is unnecessary as the temperature of the suspension does not impact desmopressin administration. Choice B is incorrect as wearing a medical identification bracelet is essential for individuals with diabetes insipidus to alert healthcare providers in case of emergencies. Choice D is incorrect as monitoring fluid intake and output is crucial when taking desmopressin to ensure proper hydration and medication effectiveness.

2. 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.

3. The nurse is caring for a client with congestive heart failure. On assessment, the nurse notes that the client is dyspneic and that crackles are audible on auscultation. The nurse suspects excess fluid volume. What additional signs would the nurse expect to note in this client if excess fluid volume is present?

• A. Weight loss
• B. Flat neck and hand veins
• C. An increase in blood pressure
• D. A decreased central venous pressure (CVP)

Correct answer: C

Rationale: An increase in blood pressure is a common sign of fluid volume excess in clients with congestive heart failure due to the increased amount of fluid in the vascular system. Weight loss (Choice A) is not typically associated with fluid volume excess. Flat neck and hand veins (Choice B) are signs of fluid volume deficit, not excess. A decreased central venous pressure (CVP) (Choice D) is not expected in a client with fluid volume excess.

4. The nurse is caring for a client with syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following clinical findings should the nurse expect?

• A. Hyponatremia
• B. Hyperkalemia
• C. Hypercalcemia
• D. Hypernatremia

Correct answer: A

Rationale: In SIADH, there is excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. Hyponatremia is a hallmark finding in SIADH due to the imbalance between water and sodium levels. Hyperkalemia (Choice B) is not typically associated with SIADH. Hypercalcemia (Choice C) involves elevated calcium levels, which are not directly related to SIADH. Hypernatremia (Choice D) is the opposite of what occurs in SIADH, where sodium levels are usually diluted due to water retention.

5. A client with type 1 diabetes mellitus is admitted with diabetic ketoacidosis (DKA). Which of the following interventions should be the nurse's priority?

• A. Administer intravenous insulin
• B. Start an intravenous line and infuse normal saline
• C. Monitor serum potassium levels
• D. Obtain an arterial blood gas (ABG)

Correct answer: B

Rationale: The correct answer is to start an intravenous line and infuse normal saline. In diabetic ketoacidosis (DKA), the priority intervention is fluid resuscitation with normal saline to restore intravascular volume and improve perfusion. Administering insulin without first addressing dehydration and electrolyte imbalances can lead to further complications. Monitoring serum potassium levels and obtaining an arterial blood gas (ABG) are important aspects of DKA management but come after initial fluid resuscitation.
