Question 1 of 5
A 62-year-old woman with type 2 diabetes, hypertension, renal impairment (creatinine 146 μmol/L) and mild congestive cardiac failure has poor diabetic control (HbA1c = 10.5 per cent), despite treatment with maximum doses of a sulfonylurea. Her body mass index (BMI) is 26. Which of the following would be most appropriate pharmacotherapy?
Correct Answer: A
Rationale: Poor glycemic control (HbA1c 10.5%) despite max sulfonylurea in type 2 diabetes with renal impairment and CHF needs escalation. Insulin replaces sulfonylurea, offering precise control without renal clearance issues, most appropriate here. Rosiglitazone risks fluid retention, worsening CHF. Bisoprolol, a beta-blocker, and rimonabant (withdrawn) don't address glycemia. Metformin is contraindicated with creatinine 146 μmol/L (eGFR <30-45) due to lactic acidosis risk. Insulin's flexibility and safety in this complex case optimize outcomes, critical for reducing complications.
Question 2 of 5
A 79-year-old patient is taking a diuretic for treatment of hypertension. This patient is very
Correct Answer: A
Rationale: The nurse will know that it is important to teach the patient to take extra precautions when standing up because of the potential risk of orthostatic hypotension and falls while taking a diuretic for hypertension. Orthostatic hypotension is a common side effect of diuretics, which can lead to dizziness or lightheadedness when changing positions, particularly when standing up quickly. This can increase the risk of falls and injury, especially in elderly patients like this 79-year-old individual. Therefore, the teaching point about taking extra precautions while standing up is crucial for the safety and well-being of the patient.
Question 3 of 5
When should a patient taking omeprazole be administered the medication?
Correct Answer: C
Rationale: Omeprazole is a proton pump inhibitor commonly used to treat conditions such as acid reflux and ulcers. It is typically recommended to be taken in the morning on an empty stomach, at least 30 minutes before the first meal of the day. This is because omeprazole works best when the stomach is empty to ensure optimal absorption and effectiveness of the medication. Taking omeprazole with food or at other times of the day may reduce its potency and could lead to suboptimal results in managing the patient's condition.
Question 4 of 5
A patient has been on TPN for 1 month, and there is an order to discontinue TPN tomorrow. The nurse contacts the health care provider because sudden interruption of TPN therapy may cause which condition?
Correct Answer: D
Rationale: Sudden discontinuation of TPN can cause hypoglycemia due to the abrupt cessation of dextrose infusion. The nurse should gradually taper TPN or provide a dextrose solution to prevent this. Dehydration (A), tremors (B), and urinary retention (C) are not typical complications of TPN discontinuation.
Question 5 of 5
Amoxicillin is prescribed for a patient who has a respiratory infection. The nurse is teaching the patient about this medication and realizes that more teaching is needed when the patient makes which statement?
Correct Answer: A
Rationale: Amoxicillin is an antibiotic that is generally well-absorbed with or without food, but taking it with food can help reduce gastrointestinal side effects such as nausea. The statement 'This medication should not be taken with food' indicates a misunderstanding, as food does not significantly impair its absorption. The other statements are correct: completing the prescription prevents antibiotic resistance, reporting genital itching is important for identifying potential yeast infections, and excess bleeding could indicate a rare but serious side effect like thrombocytopenia.
