Nursing Elites

1. A client with a history of myocardial infarction (MI) is prescribed nitroglycerin (Nitrostat) for chest pain. Which instruction should the nurse provide?

• A. Take the medication with food.
• B. Swallow the tablet whole.
• C. Take the medication at bedtime.
• D. Place the tablet under your tongue.

Correct answer: D

Rationale: The correct instruction for a client prescribed nitroglycerin (Nitrostat) for chest pain is to place the tablet under the tongue. This route allows for rapid absorption of the medication, providing quick relief for chest pain associated with myocardial infarction.

2. A patient with glaucoma is prescribed timolol eye drops. What is the primary action of this medication?

• A. Reduce intraocular pressure
• B. Dilate the pupils
• C. Constrict the pupils
• D. Enhance tear production

Correct answer: A

Rationale: Timolol eye drops are prescribed to reduce intraocular pressure in patients with glaucoma. By decreasing the pressure within the eye, timolol helps prevent damage to the optic nerve, which is crucial in managing glaucoma and preserving vision. Dilating or constricting the pupils or enhancing tear production are not the primary actions of timolol eye drops.

3. In a client with liver cirrhosis experiencing confusion and disorientation, what condition is most likely causing these symptoms?

• A. Hepatic encephalopathy
• B. Hypoglycemia
• C. Electrolyte imbalance
• D. Dehydration

Correct answer: A

Rationale: Hepatic encephalopathy is the most likely condition causing confusion and disorientation in a client with liver cirrhosis. This condition is a common complication of liver cirrhosis and is characterized by cognitive impairment due to elevated ammonia levels in the blood. The build-up of ammonia affects brain function, leading to symptoms such as confusion, disorientation, and altered consciousness. Hypoglycemia (choice B) may present with confusion but is less likely in a client with liver cirrhosis without a history of diabetes or insulin use. Electrolyte imbalance (choice C) and dehydration (choice D) can contribute to confusion but are not the primary causes in a client with liver cirrhosis experiencing these symptoms.

4. A patient with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). What is the priority nursing action?

• A. Administer regular insulin intravenously.
• B. Give oral hypoglycemic agents.
• C. Administer sodium bicarbonate.
• D. Provide a high-calorie diet.

Correct answer: A

Rationale: The priority nursing action for a patient with type 1 diabetes mellitus admitted with diabetic ketoacidosis (DKA) is to administer regular insulin intravenously. Insulin helps to lower blood glucose levels and correct acidosis, which are critical in managing DKA. Administering oral hypoglycemic agents is not appropriate in the acute setting of DKA as they may not work quickly enough compared to intravenous insulin. While sodium bicarbonate may be used to correct acidosis, insulin administration is the priority to address both hyperglycemia and acidosis simultaneously. Providing a high-calorie diet is not suitable initially in DKA management; the main focus is on stabilizing the patient's condition through insulin therapy and fluid/electrolyte correction.

5. A client has developed hepatic encephalopathy secondary to cirrhosis and is receiving care on the medical unit. The client's current medication regimen includes lactulose four times daily. What desired outcome should the nurse relate to this pharmacologic intervention?

• A. Two to three soft bowel movements daily
• B. Significant increase in appetite and food intake
• C. Absence of nausea and vomiting
• D. Absence of blood or mucus in stool

Correct answer: A

Rationale: Lactulose is used in hepatic encephalopathy to reduce blood ammonia levels by promoting bowel movements. The desired outcome of lactulose therapy is typically two to three soft bowel movements daily, which helps in eliminating excess ammonia from the body, thus improving the client's condition.
