A nurse is providing teaching to a client about recognizing manifestations of an impending cardiac arrest. Which of the following manifestations should the nurse include in the teaching?

Muscular aches in the leg

Profound fatigue

Severe headache

Ringing in the ears

Answer and Explanation

The Correct Answer is B

A. Muscular aches in the leg: Muscular aches in the leg are not typically indicative of an impending cardiac arrest. While leg pain or cramping can be associated with peripheral vascular disease or venous insufficiency, they are not specific signs of cardiac arrest.

B. Profound fatigue: Profound fatigue can be a warning sign of an impending cardiac arrest. Fatigue or weakness can result from inadequate blood flow to the heart muscle, which may occur prior to a cardiac event. Additionally, systemic effects of cardiovascular compromise can lead to generalized weakness and fatigue.

C. Severe headache: While severe headache can be associated with conditions such as hypertension or intracranial bleeding, it is not a typical manifestation of an impending cardiac arrest. Headaches may occur as a result of stress or anxiety related to the cardiac event, but they are not a direct warning sign of impending cardiac arrest.

D. Ringing in the ears: Ringing in the ears, also known as tinnitus, is not typically associated with an impending cardiac arrest. Tinnitus can result from various factors such as noise exposure, ear infections, or certain medications, but it is not considered a warning sign of impending cardiac arrest.

Correct Answer is D

Explanation

A. Lie on your back when sleeping: Lying on the back when sleeping may be recommended initially after cochlear implant surgery to avoid putting pressure on the surgical site. However, this instruction should not be included in the plan of care indefinitely. Once the client is comfortable and the surgical site is healing well, they should be allowed to sleep in any position that is comfortable for them.

B. Lie on your front when sleeping: Lying on the front when sleeping is not typically recommended after cochlear implant surgery, as it may put pressure on the surgical site and disrupt healing. This position could potentially cause discomfort and increase the risk of complications. Therefore, this instruction should not be included in the plan of care.

C. Resume your exercise routine: Resuming the exercise routine immediately after cochlear implant surgery may not be advisable. The client should be instructed to avoid strenuous activities and heavy lifting for a certain period as advised by the healthcare provider. Engaging in vigorous exercise too soon after surgery could potentially disrupt the healing process and increase the risk of complications. Therefore, this instruction should not be included in the plan of care immediately after surgery.

D. Wash your hair 24 hr after surgery: After cochlear implant insertion, it is important to keep the surgical site clean to prevent infection. Washing the hair 24 hours after surgery helps to maintain cleanliness and hygiene without disrupting the surgical site. It is typically safe to wash the hair after this period as long as gentle care is taken to avoid excessive manipulation of the implant site.

A. Creatine kinase (CK) test B. Creatine kinase-myocardial band (CK-MB) test C. Brain natriuretic peptide (BNP) test D. Troponin T test

Correct Answer is D

Explanation

A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.

B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.

C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.

D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.
