Prior to giving digoxin, the practical nurse (PN) assesses that a 2-month-old infant's heart rate is 120 beats/minute. Based on this, what action should the PN take?
Administer the medication and alert the charge nurse
Hold the medication and document cardiac assessment
Administer the medication and document the heart rate
Hold the medication and recheck the heart rate in 1 hour
The Correct Answer is C
The correct answer and explanation is:
c) Administer the medication and document the heart rate.
This is the action that the PN should take prior to giving digoxin to a 2-month-old infant whose heart rate is 120 beats/minute. Digoxin is a cardiac glycoside that is used to treat heart failure and arrhythmias. It has a narrow therapeutic range and can cause serious side effects such as bradycardia, hypotension, and toxicity. Therefore, it is important to monitor the client's vital signs before and after administering the medication. A normal heart rate for a 2-month-old infant is 100–190 beats/minute, so 120 beats/minute is within the normal range and does not indicate a need to hold the medication. The PN should administer the medication as prescribed and document the heart rate and any other relevant findings.
a) Administer the medication and alert the charge nurse.
This is not the action that the PN should take prior to giving digoxin to a 2-month-old infant whose heart rate is 120 beats/minute. Alerting the charge nurse is not necessary, as the heart rate is normal and does not indicate a problem with the medication or the client's condition. The PN should administer the medication as prescribed and document the heart rate and any other relevant findings.
b) Hold the medication and document cardiac assessment.
This is not the action that the PN should take prior to giving digoxin to a 2-month-old infant whose heart rate is 120 beats/minute. Holding the medication is not appropriate, as the heart rate is normal and does not indicate a contraindication or a risk of adverse effects from the medication. The PN should administer the medication as prescribed and document the heart rate and any other relevant findings.
d) Hold the medication and recheck the heart rate in 1 hour.
This is not the action that the PN should take prior to giving digoxin to a 2-month-old infant whose heart rate is 120 beats/minute. Holding the medication and rechecking the heart rate in 1 hour is not necessary, as the heart rate is normal and does not indicate a need for further evaluation or intervention. The PN should administer the medication as prescribed and document the heart rate and any other relevant findings.

Correct Answer is ["A","C","D","E"]
Explanation
Choice A rationale:
Verapamil is a calcium channel blocker and is expected to decrease heart rate by inhibiting calcium influx into cardiac cells, particularly in the SA (sinoatrial) node, where it can slow down the heart's electrical impulses.
Choice B rationale:
Increased contractility is not an expected outcome of verapamil use. In fact, verapamil's main action is to decrease myocardial contractility, making it useful for treating conditions like angina and atrial fibrillation.
Choice C rationale:
Verapamil is known to dilate coronary arteries, which can improve blood flow to the heart muscle and relieve symptoms of angina.
Choice D rationale:
Reduced blood pressure is an expected outcome of verapamil use due to its vasodilatory effects on peripheral blood vessels. This can be beneficial in treating hypertension and angina.
Choice E rationale:
Relieved chest pain is an expected outcome of verapamil use, particularly in the case of variant angina (Prinzmetal's angina), as it helps to relax coronary arteries and reduce coronary artery spasm, which is a common cause of chest pain in this condition.
Correct Answer is ["1"]
Explanation
This is the correct answer because the concentration of cefazolin after reconstitution is 1 gram/2.5 mL, which is equivalent to 400 mg/1 mL. Therefore, to administer 400 mg of cefazolin, the PN should draw up 1 mL of the reconstituted solution. This can be calculated using the formula:
Desired dose / Available dose = Volume to administer
400 mg / 1000 mg = x mL / 2.5 mL
x = (400 x 2.5) / 1000
x = 1 mL
