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 B
Explanation
Choice A reason: Glucose Dextrose Oral (GDO) is not typically used in the immediate management of anaphylactic shock. Anaphylaxis requires rapid treatment to address severe allergic reactions and GDO does not play a role in this emergency situation.
Choice B reason: Epinephrine (Adrenaline) is the first-line treatment for anaphylactic shock. It works quickly to improve breathing, stimulate the heart, raise a dropping blood pressure, reverse hives, and reduce swelling of the face, lips, and throat.
Choice C reason: Dexamethasone (Decadron) is a corticosteroid that may be used in the treatment of anaphylaxis to reduce inflammation. However, it is not the first medication administered due to its slower onset of action compared to epinephrine.
Choice D reason: 0.9% Normal Saline is used for intravenous fluid resuscitation in anaphylactic shock but is secondary to the administration of epinephrine. It helps to maintain blood pressure and is important in the overall management but not the first medication given.
Correct Answer is A
Explanation
Choice A reason: Administering prednisone before the test may be part of a premedication protocol for clients with a history of allergic reactions to contrast media. However, this is typically done for iodinated contrast used in CT scans, not for gadolinium-based contrast agents used in MRA.
Choice B reason: Consulting with the provider to change to a CT scan would not be appropriate if the client is allergic to iodinated contrast dye, as CT scans commonly use iodinated contrast. MRA typically uses gadolinium-based contrast agents, which may be safer for clients with iodine allergies.
Choice C reason: Assessing the alkaline phosphatase level is not directly related to preparing a client with a contrast dye allergy for an MRA. Alkaline phosphatase is an enzyme measured in blood tests and is not specific to contrast media allergies.
Choice D reason: Obtaining the client's allergy history to seafood is not necessary for MRA preparation. While there is a common misconception that seafood allergies are related to iodinated contrast allergies, the evidence does not support this association.
