A client with gonorrhea is treated with a single IM dose of ceftriaxone (Rocephin) and is given a prescription for doxycycline 100mg BID for 7 days, The nurse explains to the client that this combination is prescribed to
Treat any coexisting chlamydial infection.
Eradicate any resistant strains of N. gonorrhoeae.
Prevent reinfection during treatment.
Prevent the development of resistant organisms.
The Correct Answer is A
A. Gonorrhea and chlamydia often coexist in individuals, and doxycycline is prescribed to treat chlamydia in addition to ceftriaxone for gonorrhea. Treating both infections is crucial to reduce the risk of complications and reinfection.
B. While ceftriaxone is effective against N. gonorrhoeae, doxycycline is used to treat chlamydia, not to eradicate resistant strains of gonorrhea.
C. Reinfection during treatment can be minimized with both medications, but the primary purpose of doxycycline is to treat a possible co-infection with chlamydia.
D. This combination therapy does not primarily aim to prevent the development of resistant organisms but to treat both infections effectively.

Correct Answer is A
Explanation
A. Intermittent claudication is characterized by cramping pain in the legs during physical activity, such as walking, due to insufficient blood flow, typically caused by peripheral arterial disease (PAD). This statement aligns with the symptoms of claudication.
B. Shortness of breath during physical exertion is more indicative of cardiovascular or pulmonary issues, not intermittent claudication.
C. Swelling in the feet from standing for extended periods is more consistent with venous insufficiency rather than intermittent claudication.
D. Pain in the fingers due to cold weather suggests Raynaud’s phenomenon, not intermittent claudication.
Correct Answer is C
Explanation
A. This is an underestimation due to a miscalculation of the dose rate.
B. This is an overestimation due to a miscalculation of the dose rate.
C. 1. Calculate the desired dose of dobutamine:
Desired dose (mcg/min) = Dose per kg (mcg/kg/min) x Weight (kg)
Desired dose (mcg/min) = 12 mcg/kg/min x 75 kg = 900 mcg/min
2. Convert mcg/min to mg/hr:
900 mcg/min x 60 min/hr = 54,000 mcg/hr
54,000 mcg/hr ÷ 1000 mcg/mg = 54 mg/hr
3. Calculate the concentration of dobutamine in the solution:
Concentration (mg/mL) = Total amount of dobutamine (mg) / Total volume (mL)
Concentration (mg/mL) = 1000 mg (1 g) / 250 mL = 4 mg/mL
4. Calculate the infusion rate (mL/hr):
Infusion rate (mL/hr) = Desired dose (mg/hr) / Concentration (mg/mL)
Infusion rate (mL/hr) = 54 mg/hr / 4 mg/mL = 13.5 mL/hr
5. Round to the nearest whole number:
Infusion rate (mL/hr) = 14 mL/hr
Therefore, the IV pump should be programmed for 14 mL/hr.
D. This is an overestimation due to a miscalculation of the dose rate.
