A nurse is reinforcing teaching about laboratory testing with a client.

Which of the following findings should the nurse include as an indicator of infection?

Increased erythrocyte sedimentation rate

Decreased platelets

Increased iron level

Decreased hemoglobin

Answer and Explanation

The Correct Answer is A

Explanation

A. Increased erythrocyte sedimentation rate

A. Increased erythrocyte sedimentation rate (ESR) is a non-specific marker of inflammation in the body. In the presence of an infection, the ESR tends to rise due to increased levels of acute-phase reactants, such as fibrinogen and globulins. However, it is important to note that an increased ESR alone does not diagnose a specific infection but rather indicates the presence of inflammation or infection.

Decreased platelets in (option B) should not be included because they are not typically associated with infection. Low platelet levels (thrombocytopenia) may occur due to various reasons, such as certain medications, immune disorders, or bone marrow problems, but they are not directly linked to infections.

Increased iron level in (option C) should not be included because it is not a typical finding in an active infection. In fact, during an infection, iron levels tend to decrease in response to the body's efforts to withhold iron from pathogens, as most microorganisms require iron for their growth and survival.

Decreased haemoglobin in (option D) should not be included because it is not directly indicative of an infection. A decrease in hemoglobin levels may be associated with conditions such as anaemia, blood loss, or certain chronic diseases, but it is not a specific marker for infection.

Correct Answer is C

Explanation

Explanation

C. Position the client on their left side

The symptoms of feeling dizzy, racing heart, and becoming pale while lying on their back are consistent with supine hypotensive syndrome or vena cava syndrome. This condition occurs when the pregnant uterus compresses the vena cava, reducing blood flow back to the heart and causing a drop-in blood pressure.

Positioning the client on their left side helps alleviate the pressure on the vena cava, allowing for improved blood flow and preventing further symptoms. This position optimizes blood circulation and reduces the risk of complications. The nurse should assist the client in turning onto their left side and ensure they are comfortable.

Providing the client with a glass of orange juice (option A) is not recommended as it may be helpful in cases of low blood sugar or hypoglycemia, but it is not the most appropriate action in this scenario.

Instructing the client to take a brisk walk (option B) is not recommended since physical exertion can further worsen the symptoms and increase the risk of complications.

Checking the client's temperature (option D) is not necessary as the reported symptoms are not indicative of a fever or infection.

Therefore, the most appropriate action for the nurse to take in this situation is to position the client on their left side (option C).

A. Dry mucous membranes B. Trousseau's sign C. Hyperactive reflexes D. Irregular heart rate

Correct Answer is D

Explanation

Hyperkalemia refers to an elevated level of potassium in the blood. It can have various manifestations, and one of the critical effects of hyperkalemia is its impact on cardiac function. High levels of potassium can disrupt the normal electrical conduction in the heart, leading to arrhythmias or irregular heart rate. These arrhythmias can range from mild palpitations to more severe and life-threatening conditions like ventricular fibrillation.

Dry mucous membranes are more commonly associated with dehydration or reduced fluid intake. Hyperkalemia does not directly cause dry mucous membranes.

Trousseau's sign is a clinical manifestation of hypocalcemia, not hyperkalemia. It is characterized by carpal spasm induced by inflating a blood pressure cuff above the client's systolic blood pressure for a few minutes.

Hyperactive reflexes are commonly seen in conditions such as hyperthyroidism or certain neurologic disorders. They are not directly related to hyperkalemia.
