Which assessment finding requires nursing intervention prior to the administration of a prescribed dose of digoxin to an adult?
Apical pulse rate of 50 beats/minute.
Irregular apical pulse rhythm.
Presence of a systolic heart murmur.
Apical pulse heard best at the pulmonic site.
The Correct Answer is A
Choice A reason: Apical pulse rate of 50 beats/minute requires nursing intervention prior to the administration of digoxin, which is a medication that slows down and strengthens the heartbeat. Digoxin can cause bradycardia, which is a slow heart rate below 60 beats/minute. Bradycardia can lead to inadequate blood flow and oxygen delivery to the body. The nurse should withhold the dose of digoxin and notify the prescriber if the apical pulse rate is below 60 beats/minute.
Choice B reason: Irregular apical pulse rhythm does not require nursing intervention prior to the administration of digoxin, which is a medication that treats arrhythmias, which are irregular heart rhythms. Digoxin can correct or prevent some types of arrhythmias, such as atrial fibrillation or flutter. The nurse should monitor the apical pulse rhythm and report any changes to the prescriber, but it is not a reason to withhold the dose of digoxin.
Choice C reason: Presence of a systolic heart murmur does not require nursing intervention prior to the administration of digoxin, which is a medication that improves the pumping function of the heart. A systolic heart murmur is a sound that occurs when the heart contracts and blood flows through a narrow or leaky valve. Digoxin can reduce the symptoms of heart failure, such as shortness of breath, fatigue, and edema, which may be associated with a systolic heart murmur. The nurse should document the presence and characteristics of the heart murmur, but it is not a reason to withhold the dose of digoxin.
Choice D reason: Apical pulse heard best at the pulmonic site does not require nursing intervention prior to the administration of digoxin, which is a medication that affects the electrical activity and contractility of the heart. The apical pulse is the heartbeat heard at the apex of the heart, which is located at the fifth intercostal space on the left midclavicular line. The pulmonic site is located at the second intercostal space on the left sternal border, where the sound of blood flow through the pulmonary valve can be heard. The nurse should listen to the apical pulse at the correct location, but it is not a reason to withhold the dose of digoxin.

Correct Answer is []
Explanation
Body System: Respiratory
The correct choice is A
Choice A: Assess lung sounds This is the correct choice because the client may have developed an allergic reaction to vancomycin, which can cause bronchospasm and wheezing. Assessing lung sounds can help the nurse monitor the client’s respiratory status and intervene if needed.
Choice B: Provide a calm environment This is not the correct choice because providing a calm environment is not specific to the respiratory system. It may help the client feel more comfortable, but it does not address the potential respiratory complications of an allergic reaction.
Choice C: Pain medication This is not the correct choice because pain medication is not related to the respiratory system. The client did not report any pain, and pain medication may have adverse effects on the respiratory system, such as respiratory depression.
Choice D: Chest x-ray This is not the correct choice because a chest x-ray is not indicated for the client at this time. A chest x-ray is a diagnostic test that can show abnormalities in the lungs, such as pneumonia or pleural effusion. However, the client’s symptoms are more likely caused by an allergic reaction, which would not be visible on a chest x-ray.
Body System: Cardiovascular
The correct answer is A, B, and C. Here are the explanations for each choice:
Choice A: Monitor vital signs continuously. This is a correct and appropriate nursing intervention for the cardiovascular system. The client may have hypotension, tachycardia, or arrhythmias due to anaphylaxis or the effects of medications. Continuous monitoring can help detect any changes and guide interventions accordingly .
Choice B: Provide warmth. This is also a correct and appropriate nursing intervention for the cardiovascular system. The client may lose heat due to vasodilation, sweating, or exposure during the procedure. Providing warmth can help prevent hypothermia and shivering, which can increase oxygen demand and worsen cardiac function. Providing warmth can also improve comfort and reduce anxiety .
Choice C: Defibrillator at bedside. This is another correct and appropriate nursing intervention for the cardiovascular system. The client is at risk of cardiac arrest due to anaphylaxis, bradycardia, or pacemaker malfunction. Having a defibrillator at bedside can facilitate prompt resuscitation if needed.
Choice D: ECHO. This is an incorrect and inappropriate nursing intervention for the cardiovascular system. ECHO is a diagnostic test that uses ultrasound waves to create images of the heart and its structures. It can help evaluate the client’s cardiac function, valve function, and presence of any complications such as pericardial effusion or tamponade. However, this is not a priority intervention for the client who is experiencing an anaphylactic reaction and needs immediate treatment to stabilize her condition. ECHO can be done later after the client recovers from the acute episode.
Body System: Immunological
The correct answer is **A and D**.
- Choice A: Administer antihistamine. This is a correct and appropriate nursing intervention for the immunological system. The client is having an anaphylactic reaction to vancomycin, which is a type of hypersensitivity reaction mediated by IgE antibodies. Antihistamines, such as diphenhydramine, can block the effects of histamine, which is a major mediator of allergic inflammation and symptoms. Antihistamines can help reduce itching, hives, flushing, and bronchoconstriction¹².
- Choice B: IV fluids. This is an incorrect and inappropriate nursing intervention for the immunological system. IV fluids are not directly related to the immune response or the allergic reaction. IV fluids are mainly used to maintain hydration, electrolyte balance, and blood pressure. However, IV fluids may be indicated for the client as part of the cardiovascular or renal system interventions³.
- Choice C: Assess rash. This is an incorrect and inappropriate nursing intervention for the immunological system. Assessing rash is not a specific intervention for the immune response or the allergic reaction. Assessing rash is part of the general assessment of the client's skin condition, which may reflect other factors such as infection, inflammation, or drug toxicity. However, assessing rash may be helpful to monitor the severity and progression of the allergic reaction and the effectiveness of the treatment⁴.
- Choice D: Administer steroid. This is a correct and appropriate nursing intervention for the immunological system. The client is having an anaphylactic reaction to vancomycin, which is a type of hypersensitivity reaction mediated by IgE antibodies. Steroids, such as methylprednisolone, can suppress the immune system and reduce the production of inflammatory mediators, such as cytokines and prostaglandins. Steroids can help decrease swelling, inflammation, and tissue damage¹².
Correct Answer is A
Explanation
Choice A reason: Eliminating use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, is an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that stabilizes mood and prevents manic episodes. NSAIDs can increase the blood levels of lithium and cause toxicity, which can manifest as nausea, vomiting, tremors, confusion, or seizures.
Choice B reason: Monitoring blood glucose levels daily is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not affect the blood sugar levels or the risk of diabetes. Blood glucose levels may be important for the general health of the client, but they are not related to lithium therapy.
Choice C reason: Notifying healthcare provider prior to dental procedures is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interact with local anesthetics or antibiotics that may be used during dental procedures. However, the client should inform the dentist about their medical history and medications, as a precaution.
Choice D reason: Avoiding consuming all foods that contain iodine is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interfere with the thyroid function or the metabolism of iodine. Iodine is an essential nutrient that is found in many foods, such as seafood, dairy products, eggs, and iodized salt. Avoiding iodine can cause deficiency and lead to goiter or hypothyroidism.
