A nurse is assisting in the plan of care for a client who has a suspected myocardial infarction. Which of the following medications should the nurse plan to administer first?

Morphine

Nitroglycerin

Aspirin

Oxygen

Answer and Explanation

The Correct Answer is D

Choice A reason : Morphine is an opioid analgesic used to relieve severe pain and can be administered to patients with myocardial infarction to alleviate chest pain and anxiety. However, it is not the first medication given as it does not address the underlying cause of the myocardial infarction, which is the formation of a blood clot in the coronary arteries.

Choice B reason : Nitroglycerin is a nitrate that helps to dilate blood vessels and improve blood flow. It can be used to relieve chest pain in myocardial infarction, but similar to morphine, it is not the initial medication of choice. The priority is to prevent further blood clotting.

Choice C reason : Administered as soon as possible to inhibit platelet aggregation and reduce clot progression.

Choice D reason : When a myocardial infarction (MI) is suspected, the priority is to address tissue hypoxia and ensure adequate oxygenation to minimize myocardial damage. Administering oxygen helps increase oxygen availability to the ischemic heart tissue, reducing further damage.

Correct Answer is B

Explanation

Choice A reason: Cough is not commonly associated with atenolol. Atenolol is a beta-blocker used to treat hypertension and is less likely to cause respiratory side effects compared to some other classes of antihypertensive medications.

Choice B reason: Bradycardia, or a slower than normal heart rate, is a well-documented adverse effect of atenolol. Atenolol works by blocking beta-1 receptors in the heart, which can reduce the heart rate. Normal heart rate ranges for infants (1 to 11 months old) are 80-160 beats per minute (BPM), and for toddlers (1-2 years old), it's 80-130 BPM. Bradycardia would be defined as a heart rate below these normal ranges. It is important for patients starting atenolol to monitor their pulse regularly and report any significant decrease in heart rate to their healthcare provider.

Choice C reason: While constipation can be a side effect of many medications, it is not a common adverse effect of atenolol. Atenolol does not typically affect the gastrointestinal system to the extent that it causes constipation.

Choice D reason: Headache is not a typical adverse effect of atenolol. While headaches can occur for a variety of reasons, they are not directly linked to the pharmacological action of atenolol on the cardiovascular system.

A. The frequency in which blood pressure is taken. B. Interventions implemented in response to a high blood pressure reading. C. The patient's response to interventions implemented. D. The person who obtained the blood pressure reading. E. The site where the blood pressure was obtained.

Correct Answer is A

Explanation

Choice A reason : Hepatomegaly, or the enlargement of the liver, is a common finding in right-sided heart failure. This condition occurs because the heart does not pump blood effectively, leading to congestion and increased pressure in the venous system, including the hepatic veins. As a result, the liver becomes engorged with blood, causing it to enlarge. The normal liver span in adults is about 10-12 cm in the midclavicular line, and any measurement above this can indicate hepatomegaly.

Choice B reason : Orthopnea, which is shortness of breath while lying flat, is more commonly associated with left-sided heart failure. In right-sided heart failure, symptoms are more related to systemic congestion, such as swelling in the legs and abdomen, rather than pulmonary symptoms like orthopnea.

Choice C reason : Dyspnea, or difficulty breathing, can be a symptom of both left and right-sided heart failure. However, in the context of right-sided heart failure, dyspnea is usually due to the accumulation of fluid in the abdominal cavity (ascites) and the increased pressure in the abdominal veins, which can compress the diaphragm and make breathing difficult.

Choice D reason : Frothy sputum is typically not a symptom of right-sided heart failure. It is more indicative of pulmonary edema, which is associated with left-sided heart failure. In right-sided heart failure, the primary issues are related to the systemic circulation and venous congestion.
