1. A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:
- A. Increase thyroid hormone production
- B. Decrease thyroid hormone production
- C. Relieve symptoms such as tachycardia and anxiety
- D. Prevent weight loss
Correct answer: C
Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.
2. Nurse Louie is developing a teaching plan for a male client diagnosed with diabetes insipidus. The nurse should include information about which hormone lacking in clients with diabetes insipidus?
- A. Antidiuretic hormone (ADH)
- B. Thyroid-stimulating hormone (TSH)
- C. Follicle-stimulating hormone (FSH)
- D. Luteinizing hormone (LH)
Correct answer: A
Rationale: Diabetes insipidus is a condition characterized by a deficiency of antidiuretic hormone (ADH). ADH plays a crucial role in regulating water balance by controlling the amount of water reabsorbed by the kidneys. Options B, C, and D are incorrect as they are not associated with diabetes insipidus. TSH (thyroid-stimulating hormone) is responsible for regulating thyroid function, while FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are involved in reproductive functions.
3. A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:
- A. Obtain a new vial of NPH insulin.
- B. Draw up the cloudy insulin as ordered.
- C. Shake the vial vigorously before drawing up the insulin.
- D. Warm the insulin to room temperature before administration.
Correct answer: B
Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.
4. A client with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). Which of the following interventions should the nurse implement first?
- 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 first intervention in the treatment of a client with diabetic ketoacidosis (DKA) is to start an intravenous line and infuse normal saline. This is essential for fluid resuscitation to restore intravascular volume and improve perfusion. Administering intravenous insulin can lead to further potassium depletion without first addressing dehydration and electrolyte imbalances. Monitoring serum potassium levels is important but should follow fluid resuscitation to avoid life-threatening hypokalemia. Obtaining an arterial blood gas (ABG) is necessary to assess the acid-base status but is not the initial priority when managing DKA.
5. An agitated, confused female client arrives in the emergency department. Her history includes type 1 diabetes mellitus, hypertension, and angina pectoris. Assessment reveals pallor, diaphoresis, headache, and intense hunger. A stat blood glucose sample measures 42 mg/dl, and the client is treated for an acute hypoglycemic reaction. After recovery, the nurse teaches the client to treat hypoglycemia by ingesting:
- A. 2 to 5 g of a simple carbohydrate.
- B. 10 to 15 g of a simple carbohydrate.
- C. 18 to 20 g of a simple carbohydrate.
- D. 25 to 30 g of a simple carbohydrate.
Correct answer: B
Rationale: The correct answer is B: 10 to 15 g of a simple carbohydrate. In the treatment of hypoglycemia, it is important to administer a specific amount of simple carbohydrates to raise blood glucose levels effectively without causing hyperglycemia. 10 to 15 g of simple carbohydrates, such as glucose tablets, fruit juice, or regular soft drinks, is recommended to rapidly increase blood sugar levels in clients experiencing hypoglycemia. Choices A, C, and D are incorrect as they either provide too little or too much glucose, which may not effectively treat the hypoglycemic episode or may lead to rebound hyperglycemia.
