A nurse is preparing to administer a medication for a client through a nontunneled percutaneous central catheter. Which of the following actions should the nurse take?

Close the inline clamp.

Flush the catheter with 10 mL of 0.9% sodium chloride.

Apply a local anesthetic to the skin.

Don sterile gloves.

Answer and Explanation

The Correct Answer is B

A. Closing the inline clamp is necessary when the catheter is not in use to prevent air embolism, but it is not a required step before administering medication. The nurse should focus on flushing and checking for patency before medication administration.

B. Flushing the catheter with 10 mL of 0.9% sodium chloride before and after medication administration helps maintain patency, prevents occlusion, and ensures the catheter is functioning properly. This step is essential to avoid complications such as clot formation.

C. Applying a local anesthetic is not needed for routine medication administration through a nontunneled percutaneous central catheter. Anesthetic use is typically reserved for procedures like catheter insertion or painful dressing changes.

D. Donning sterile gloves is not required for medication administration through a central line. Clean gloves are sufficient, while sterile technique is reserved for dressing changes and catheter insertions.

Explanation

Sickle Cell Disease:
• Fatigue

Iron Deficiency Anemia:
• Ferritin level
• Fatigue
• Orthostatic hypotension

Pernicious Anemia:
• Vitamin B12 level
• Fatigue

Rationale:

• Vitamin B12 level: A decreased vitamin B12 level is characteristic of pernicious anemia, which results from impaired absorption of vitamin B12 due to intrinsic factor deficiency.

• Orthostatic hypotension: A drop in blood pressure upon standing is commonly seen in iron deficiency anemia due to reduced oxygen-carrying capacity and inadequate perfusion.

• Ferritin level: A low ferritin level indicates depleted iron stores, which is a hallmark of iron deficiency anemia.

• Fatigue: Fatigue is a common symptom in all three conditions due to reduced oxygen delivery to tissues. In sickle cell disease, fatigue results from chronic hemolysis and vaso-occlusive episodes. In iron deficiency anemia, it is caused by insufficient hemoglobin production. In pernicious anemia, fatigue results from ineffective erythropoiesis due to vitamin B12 deficiency.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"D"}

Explanation

The nurse should first address the client's chest pain followed by the client's irregular heart rate.

Rationale:

Chest pain is the priority concern as it indicates an acute coronary event (ST-elevation myocardial infarction, STEMI). Immediate interventions such as oxygen, nitroglycerin, and pain management are required to reduce myocardial oxygen demand and prevent further cardiac damage.

Irregular heart rate must be addressed next, as tachycardia and arrhythmias can increase myocardial workload and worsen ischemia. Monitoring and possible antiarrhythmic interventions may be required to stabilize cardiac function.

Incorrect:

Troponin levels: Elevated troponin confirms myocardial injury but does not require immediate intervention; managing the ongoing ischemia is the priority.

Oxygen saturation: The client's oxygen saturation is 93% on room air, which is adequate. Oxygen therapy is not the first priority unless levels drop further.

Hyperlipidemia: While a cardiovascular risk factor, it is not an acute concern during an MI. Long-term management is necessary but not the immediate priority.

C-reactive protein: Elevated CRP indicates inflammation but does not require urgent intervention in the acute phase of MI.
