A patient is scheduled to have a pacemaker implanted at 0800 in the cardiac cath lab. The night shift nurse has an order to draw labs, check the patient's vital signs, and start antibiotics prior to the day shift arriving. The nurse understands that the antibiotics are intended to?
Treat a superinfection in the patient
Provide empiric therapy
Provide prophylactic therapyу
Provide definitive therapy
The Correct Answer is C
A. Treat a superinfection in the patient.: A superinfection occurs when normal flora are disrupted by prolonged antibiotic use, allowing resistant organisms to overgrow. The client has not yet received antibiotics or shown signs of secondary infection.
B. Provide empiric therapy.: Empiric therapy refers to the administration of antibiotics based on the most likely cause of infection before culture results are available. Since the patient is not currently infected and is only preparing for surgery, empiric therapy is not the purpose.
C. Provide prophylactic therapy.: Prophylactic antibiotic therapy is given before certain surgical or invasive procedures to prevent potential infection. Administering antibiotics prior to pacemaker implantation reduces the risk of postoperative infections, such as endocarditis or device-related infections.
D. Provide definitive therapy.: Definitive therapy is used when the specific causative organism has been identified through cultures and sensitivity testing. Because no infection has been diagnosed in this patient, definitive therapy is not appropriate in this preoperative context.

Correct Answer is ["63"]
Explanation
Total Volume: 500 mL
Total Time: 8 hours
Calculate the infusion rate in milliliters per hour (mL/hr).
Infusion rate (mL/hr) = Total volume (mL) / Total time (hr)
= 500 mL / 8 hr
= 62.5 mL/hr.
Round the answer to the nearest whole number.
= 63 mL/hr.
Correct Answer is A
Explanation
A. Impotence.: Cimetidine, an H2 receptor antagonist, can cause endocrine-related adverse effects such as impotence, decreased libido, and gynecomastia in men. Cimetidine can block androgen receptors and increase prolactin levels, altering normal hormonal balance.
B. Hair growth.: Cimetidine does not promote hair growth. Excessive hair growth (hirsutism) is unrelated to H2 blockers and is more commonly associated with hormonal imbalances or specific endocrine disorders rather than this medication.
C. Priapism.: Prolonged, painful erection (priapism) is not a known side effect of cimetidine. It is more often associated with certain psychiatric medications or erectile dysfunction drugs that affect vascular blood flow.
D. Hypersecretion of stomach acid.: Cimetidine decreases, not increases, gastric acid production by blocking histamine receptors in the stomach lining. It is used to treat peptic ulcer disease, GERD, and gastritis by reducing acid secretion and promoting mucosal healing.
