A nurse in the emergency department is caring for a client who took 3 nitroglycerin tablets sublingually for chest pain. The client reports relief from the chest pain but now he is experiencing a headache. Which of the following statements should the nurse make?
"A headache is an indication of an allergy to the medication."
"A headache indicates tolerance to the medication."
"A headache is likely due to the anxiety about the chest pain."
"A headache is an expected adverse effect of the medication."
The Correct Answer is D
A headache is a common and expected adverse effect of nitroglycerin, due to its vasodilating action. The client can take an over-the-counter analgesic to relieve the headache, unless contraindicated.
"A headache is an indication of an allergy to the medication." is not correct, as a headache is not a sign of an allergic reaction to nitroglycerin. An allergic reaction would manifest as rash, itching, swelling, or difficulty breathing.
"A headache indicates tolerance to the medication." is not accurate, as a headache does not indicate tolerance to nitroglycerin. Tolerance would manifest as reduced or absent relief from anginal pain.
"A headache is likely due to the anxiety about the chest pain." is not plausible, as a headache is not likely due to the anxiety about the chest pain. Anxiety would manifest as nervousness, restlessness, palpitations, or sweating.

Correct Answer is B
Explanation
The P wave is the first wave on the ECG strip and represents the electrical activity of the atria. It reflects the depolarization of the atrial myocardium, which is the process of changing the electrical charge of the cardiac cells from negative to positive, triggering a contraction. The P wave precedes the QRS complex, which represents ventricular depolarization, and the T wave, which represents ventricular repolarization.
The other options are not correct because:
a. Slow repolarization of ventricular Purkinje fibers. This statement is incorrect because it describes the U wave, which is a small and sometimes invisible wave that follows the T wave on the ECG strip. It reflects the repolarization of the ventricular Purkinje fibers, which are specialized cardiac cells that conduct electrical impulses to the ventricles. The U wave is more prominent in conditions that cause hypokalemia, such as diuretic use or vomiting.
c. Early ventricular repolarization. This statement is incorrect because it describes the ST segment, which is the flat line between the QRS complex and the T wave on the ECG strip. It reflects the early phase of ventricular repolarization, which is the process of restoring the electrical charge of the cardiac cells to negative after a contraction. The ST segment can be elevated or depressed in conditions that cause myocardial ischemia or injury, such as angina or myocardial infarction.
d. Ventricular depolarization. This statement is incorrect because it describes the QRS complex, which is the largest and most visible wave on the ECG strip. It reflects the depolarization of the ventricular myocardium, which triggers a ventricular contraction. The QRS complex follows the P wave and precedes the T wave on the ECG strip.
Correct Answer is ["1"]
Explanation
To calculate the number of tablets, divide the total dose by the dose per tablet. In this case, the total dose is 1.5 mg / 3 = 0.5 mg and the dose per tablet is 0.5 mg. Therefore,
(number of tablets) = (0.5 mg) / (0.5 mg) = 1 tablet
Round the answer to the nearest tenth and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should administer 1 tablet per dose.
