The nurse is instructing the client on the correct way to take nitroglycerin as needed for chest pain:
Two tablets PO (by mouth) every 15 minutes.
One tablet SL (sublingual) every 15 minutes, up to 5 times.
One tablet PO (by mouth) every one hour, up to 5 times.
One tablet SL (sublingual) every 5 minutes, up to 3 times.
The Correct Answer is D
Choice A reason: Taking two tablets PO every 15 minutes is not the standard protocol for nitroglycerin administration for chest pain. This method could lead to an overdose and significant hypotension (low blood pressure), which can be dangerous.
Choice B reason: One tablet SL every 15 minutes, up to 5 times, is also not the standard protocol. While sublingual administration is correct, the frequency and the total number of doses are higher than recommended, which could result in adverse effects such as headache, dizziness, or a severe drop in blood pressure.
Choice C reason: One tablet PO every one hour, up to 5 times, is not a recommended method for acute chest pain relief from angina. Oral administration does not provide the rapid onset of action required for acute angina relief.
Choice D reason: One tablet SL every 5 minutes, up to 3 times, is the correct protocol for nitroglycerin administration when experiencing chest pain due to angina. If pain persists after the first dose, the patient can take a second dose after 5 minutes, and if needed, a third dose after another 5 minutes. If chest pain continues after three doses in 15 minutes, emergency medical help should be sought immediately.

Correct Answer is C
Explanation
Choice A reason: A heart rate of 60/min is within the normal range for an adult, and while it may be considered on the lower end, it is not in itself an indication to increase dopamine dosage. Dopamine is used to increase heart rate and cardiac output, but a rate of 60/min does not typically warrant an increase in dosage unless accompanied by other signs of inadequate perfusion.
Choice B reason: An oxygen saturation of 95% is within the normal range for arterial blood gases and is not an indication to increase dopamine dosage. Oxygen saturation reflects the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.
Choice C reason: A blood pressure of 90/50 mm Hg is considered low and can be an indication for increasing the dopamine dosage in a client with hypovolemic shock. Dopamine increases blood pressure by vasoconstriction and increasing cardiac output, which is critical in managing shock.
Choice D reason: A respiratory rate of 14/min is within the normal range for adults and is not an indication to increase dopamine dosage. The respiratory rate should be monitored for changes that could indicate worsening of the client's condition, but on its own, it does not dictate adjustments to dopamine therapy.
Correct Answer is D
Explanation
Choice A reason: Applying antibiotic ointment to the lesions is not recommended for the treatment of genital herpes, which is caused by a virus, not bacteria. Antiviral medications are the appropriate treatment for managing herpes outbreaks.
Choice B reason: Natural skin condoms are not effective in preventing the transmission of genital herpes because the virus can pass through the natural membrane. The use of latex or polyurethane condoms is recommended as they are more effective in reducing the risk of transmission.
Choice C reason: Expecting lesions to resolve in 6 weeks may not be accurate as the duration of a herpes outbreak can vary. Most herpes lesions tend to resolve within 2 to 4 weeks. However, the virus remains in the body and can cause recurrent outbreaks.
Choice D reason: The duration of medication for genital herpes depends on whether the treatment is for an initial outbreak, chronic suppression, or episodic therapy. For an initial outbreak, antiviral medication is typically taken for 7 to 10 days. For chronic suppression, medication might be taken daily for an extended period to prevent or reduce the frequency of outbreaks.
