Question 1 of 5
Which of the following is not a phenylpropionic derivatives:
Correct Answer: D
Rationale: Mefenamic acid is not a phenylpropionic derivative. It is classified as a fenamate, structurally related to fenamic acid. The other options (A. ibuprofen, B. fenoprofen, C. naproxen) are all examples of phenylpropionic derivatives, commonly referred to as propionic acids. These drugs have similar chemical structures and mechanisms of action, making them a distinct group within the nonsteroidal anti-inflammatory drug (NSAID) class.
Question 2 of 5
A patient is taking a cephalosporin. The nurse anticipates which appropriate nursing intervention(s) for this medication? (Select all that apply.)
Correct Answer: A
Rationale: Cephalosporins are antibiotics that can cause nephrotoxicity, particularly in patients with pre-existing renal impairment. Monitoring renal function is essential to detect any decline in kidney function early. Liver function studies are also important because cephalosporins can occasionally cause hepatotoxicity. Intravenous cephalosporins should be infused over 30 minutes to ensure proper absorption and minimize adverse effects. Mouth ulcers are not a common side effect of cephalosporins, but monitoring for superinfections, such as oral thrush, is important. Advising the patient to stop the medication when they feel better is incorrect, as it can lead to antibiotic resistance.
Question 3 of 5
An asymptomatic 46-year-old Indian woman is found to have an elevated serum calcium (2.80 mmol/L, corrected) at a 'well-woman' screening clinic. Other chemistries are normal, in particular phosphate is 0.8 mmol/L (normal range 0.8-1.45), and parathormone (PTH) is 5.4 pmol/L (normal range <0.9-5.4). She has a sedentary occupation in a northern UK city. Which of the following would be most suitable management?
Correct Answer: D
Rationale: Mild hypercalcemia (2.80 mmol/L) with borderline PTH (5.4 pmol/L) suggests primary hyperparathyroidism (PHPT), common in asymptomatic women. Alfacalcidol treats hypocalcemia, not hypercalcemia. Sevelamer binds phosphate, irrelevant here. Teriparatide increases calcium, contraindicated. Surgical parathyroidectomy suits severe cases, but mild, asymptomatic PHPT (calcium <3.0 mmol/L) warrants watchful waiting with monitoring, most suitable to assess progression without immediate intervention. This conservative approach balances risks, especially in a sedentary northern climate lacking vitamin D excess.
Question 4 of 5
The nurse is working with a graduate nurse to prepare an intravenous dose of potassium. Which statement by the graduate nurse reflects a need for further teaching?
Correct Answer: D
Rationale: The statement "The intravenous potassium dose will be given undiluted" reflects a need for further teaching. Potassium should always be diluted before administration to prevent irritation of the veins and potential adverse effects, such as phlebitis or tissue damage. Diluting the medication helps to reduce the risk of complications, making it safer for the patient. Therefore, the correct approach is to dilute intravenous potassium before administering it to the patient.
Question 5 of 5
A patient is taking nitrofurantoin. What will the nurse teach the patient?
Correct Answer: D
Rationale: The correct teaching for a patient taking oral nitrofurantoin is to rinse the mouth after taking the medication to avoid staining the teeth. Nitrofurantoin can cause a harmless but noticeable side effect of staining the teeth, so it is important for the patient to rinse their mouth thoroughly after each dose to reduce the risk of this happening. The other options provided are not accurate teachings related to nitrofurantoin.
