The nurse is caring for a client with a diagnosis of urinary tract infection. The physician has ordered an antibiotic. What is the priority prior to administering this medication?

Obtain a platelet count

Obtain a blood pressure

Obtain a urine specimen for culture and sensitivity

Obtain a PTT

Answer and Explanation

The Correct Answer is C

A. Obtain a platelet count: Platelet count is not routinely required before antibiotics for a UTI.
B. Obtain a blood pressure: Blood pressure is not a priority for a UTI but might be checked for other reasons.
C. Obtain a urine specimen for culture and sensitivity: This is the most important step. Culturing the urine helps identify the specific bacteria causing the infection and determine the most effective antibiotic. Knowing the sensitivity profile helps select the antibiotic most likely to work against that particular bacteria.
D. Obtain a PTT: PTT (partial thromboplastin time) is not routinely required before antibiotics for a UTI.

Correct Answer is B

Explanation

A. Yeast: Yeast allergies are unrelated to cefazolin or other beta-lactam antibiotics.
B. Penicillins: Cefazolin is a cephalosporin antibiotic, and there is a potential for cross-reactivity with penicillins due to their similar beta-lactam ring structure. Checking for a penicillin allergy is essential before administering cefazolin.
C. Macrolides: Macrolides have a different structure and do not cross-react with cephalosporins, so a history of macrolide allergy is not directly relevant.
D. Sulfonamides: Sulfonamides have a different chemical structure, and there is no significant cross-reactivity with cephalosporins.

A. Presence of renal or hepatic disease B. Fluid retention C. Need for diagnostic tests involving use of contrast dyes D. Weight gain E. Presence of heart failure

Correct Answer is ["A","C","E"]

Explanation

A. Presence of renal or hepatic disease: Metformin, commonly prescribed for type 2 diabetes, is primarily excreted by the kidneys. Patients with renal impairment are at increased risk of metformin accumulation, potentially leading to lactic acidosis. Assessing for the presence of renal or hepatic disease helps determine the appropriate dosage of metformin and reduces the risk of adverse effects.
B. Fluid retention: Metformin does not typically cause fluid retention; however, monitoring for signs of fluid retention is important, especially in patients with underlying conditions such as heart failure, as fluid retention can exacerbate their condition.
C. Need for diagnostic tests involving the use of contrast dyes: Metformin can increase the risk of lactic acidosis, particularly in patients undergoing procedures involving contrast dyes. Temporarily discontinuing metformin before such procedures reduces the risk of adverse effects.
D. Weight gain: Metformin is associated with weight neutrality or even modest weight loss. Monitoring weight changes can help assess treatment response and overall health.
E. Presence of heart failure: Metformin is contraindicated in patients with severe heart failure due to the potential risk of lactic acidosis. Assessing for the presence of heart failure helps ensure safe prescribing practices and avoids potential complications associated with metformin use in this population.
