Nokea
The nurse is caring for a client with Addison's disease. The client exhibits signs of hypotension, dehydration, and confusion. The nurse should anticipate administering which of the following medications?
- A. Insulin
- B. Hydrocortisone
- C. Levothyroxine
- D. Methimazole
Correct Answer: B
Rationale: In Addison's disease, the adrenal glands do not produce enough cortisol. Hydrocortisone is a glucocorticoid medication that is used to replace deficient cortisol levels in patients with Addison's disease. It helps stabilize blood pressure and fluid balance. Insulin (Choice A) is used to manage diabetes, not Addison's disease. Levothyroxine (Choice C) is a thyroid hormone replacement used to treat hypothyroidism, not Addison's disease. Methimazole (Choice D) is used in the treatment of hyperthyroidism, not Addison's disease.

Which of the following best describes the nurse's responsibility in obtaining informed consent?
- A. The nurse is responsible for ensuring that the patient understands the procedure and has the opportunity to ask questions.
- B. The nurse should ensure that the patient signs the consent form before the procedure begins.
- C. The nurse is responsible for witnessing the patient sign the consent form and documenting the event.
- D. The nurse should delegate the task of obtaining informed consent to another healthcare provider.
Correct Answer: A
Rationale: The correct answer is A. Informed consent is a process where the healthcare provider, in this case, the nurse, ensures that the patient understands the procedure, risks, benefits, and alternatives before they agree to it. The nurse plays a crucial role in facilitating this understanding by explaining the information in a clear and understandable manner and providing the patient with the opportunity to ask questions. Choice B is incorrect because merely obtaining the patient's signature on the consent form does not ensure that the patient truly understands what they are consenting to. Choice C is not fully accurate as the nurse's role goes beyond just witnessing the signature; it involves actively ensuring the patient's comprehension. Choice D is incorrect as the responsibility of obtaining informed consent should not be delegated to another healthcare provider, as it is the nurse's duty to ensure proper communication and understanding with the patient.
A client with type 1 DM is admitted to the hospital with diabetic ketoacidosis (DKA). The nurse should prioritize which action?
- A. Administering intravenous fluids.
- B. Administering oral glucose.
- C. Administering a fever-reducing medication.
- D. Administering oxygen therapy.
Correct Answer: A
Rationale: Administering intravenous fluids is the priority in treating DKA for several reasons. DKA is characterized by severe dehydration and electrolyte imbalances due to hyperglycemia. IV fluids help to correct dehydration, restore electrolyte balance, and decrease blood glucose levels. Administering oral glucose (Choice B) would be contraindicated in DKA as the primary issue is high blood glucose levels. Administering a fever-reducing medication (Choice C) is not the priority in managing DKA. Administering oxygen therapy (Choice D) may be necessary in some cases, but correcting dehydration and electrolyte imbalances take precedence in the management of DKA.
The nurse and an unlicensed nursing assistant are caring for a group of clients. Which nursing intervention should the nurse perform?
- A. Measure the client's output from the indwelling catheter.
- B. Record the client's intake and output on the I & O sheet.
- C. Instruct the client on appropriate fluid restrictions.
- D. Provide water for a client diagnosed with diabetes insipidus.
Correct Answer: C
Rationale: Instructing the client on appropriate fluid restrictions is a nursing intervention that requires professional judgment and should be performed by the nurse. In this scenario, the nurse should provide education regarding fluid restrictions based on the client's individual needs. Measuring the client's output from the indwelling catheter (choice A) and recording intake and output (choice B) can be tasks delegated to the unlicensed nursing assistant. Providing water for a client diagnosed with diabetes insipidus (choice D) is not appropriate as these clients often require careful fluid management to prevent complications.
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.
After taking glipizide (Glucotrol) for 9 months, a male client experiences secondary failure. What would the nurse expect the physician to do?
- A. Initiate insulin therapy.
- B. Switch the client to a different oral antidiabetic agent.
- C. Prescribe an additional oral antidiabetic agent.
- D. Restrict carbohydrate intake to less than 30% of the total caloric intake.
Correct Answer: A
Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.
