Nursing Elites

1. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

2. The nurse is preparing to administer NPH insulin to a client. The nurse should administer the insulin at which site for the best absorption?

• A. The deltoid muscle
• B. The anterior thigh
• C. The abdomen
• D. The gluteal muscle

Correct answer: C

Rationale: The abdomen is the preferred site for insulin injection due to its consistent absorption rate. Insulin injected into the abdomen is absorbed more consistently and predictably than in other sites. The deltoid muscle and the anterior thigh are not recommended for insulin injections due to inconsistent absorption rates. The gluteal muscle is avoided for insulin injections due to the risk of hitting the sciatic nerve or causing discomfort to the client.

3. The healthcare provider is monitoring a client with Cushing's syndrome. Which of the following findings should the healthcare provider report?

• A. Hypotension
• B. Hyperglycemia
• C. Weight loss
• D. Hypokalemia

Correct answer: B

Rationale: In Cushing's syndrome, hyperglycemia is a common finding due to increased cortisol levels leading to insulin resistance. This can have serious implications such as diabetes mellitus and should be promptly reported for appropriate management. Hypotension (choice A) is more commonly associated with Addison's disease, not Cushing's syndrome. Weight gain rather than weight loss (choice C) is typically observed in clients with Cushing's syndrome. While hypokalemia (choice D) can occur in Cushing's syndrome due to excess cortisol affecting potassium levels, it is not as critical as hyperglycemia and may not be the priority for immediate reporting.

4. 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.

5. 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.
