A clinic nurse is providing instructions to a client who is scheduled for a glucose tolerance test. Which instruction should the nurse provide to the client in preparation for the test?

Alcohol, coffee, and tea should be avoided for 36 hours before testing. Fasting is required from midnight before the test until the test is completed, although water is permitted. The client is told to discontinue insulin or oral hypoglycemic agents on the day of the test. The nurse instructs the client to consume a high-carbohydrate diet (at least 200 to 300 g of carbohydrate per day) for at least 3 days before the test and to discontinue oral contraceptives, corticosteroids, salicylates, and thiazide derivatives 3 days before the test.

The nurse is preparing to care for a client who has returned to the nursing unit following cardiac catheterization performed through the femoral vessel. The nurse checks the health care provider's (HCP's) prescription and plans to allow which client position or activity following the procedure?

After cardiac catheterization, the extremity into which the catheter was inserted is kept straight for 4 to 6 hours. The client is maintained on bed rest for 4 to 6 hours (time for bed rest may vary depending on the HCP's preference and on whether a vascular closure device was used) and the client may turn from side to side. The head is elevated no more than 30 degrees (although some HCPs prefer a lower position or the flat position) until hemostasis is adequately achieved.

A client is undergoing a series of diagnostic tests. The laboratory results indicate an increased blood urea nitrogen (BUN) to creatinine ratio. The nurse determines that which potential conditions could contribute to these results?

Causes of an increased BUN to creatinine ratio include dehydration, a catabolic state, a high-protein diet, and obstructive uropathy

The nurse is collecting a 24-hour composite urine specimen. Besides electrolytes and glucose, what other components are measured?

Composite urine collection measures specific components, such as electrolytes, glucose, protein, 17-ketosteroids, catecholamines, creatinine, and minerals.

A nurse is assessing the status of jaundice in a child with hepatitis. Which anatomical areas will provide the best data regarding the presence of jaundice?

Jaundice, if present, is best assessed in the sclera, nail beds, and mucous membranes. Generalized jaundice will appear in the skin throughout the body.

The nurse is caring for a client with metabolic alkalosis. The nurse plans care knowing that most problems of metabolic alkalosis are related to increased stimulation of what systems? Select all that apply.

Most problems of alkalosis are related to increased stimulation of the cardiac, nervous, and neuromuscular systems. Chemical reactions are also called buffer systems and are not related to most problems of alkalosis. The respiratory system is related to respiratory alkalosis and not metabolic alkalosis.

A client has just returned from the cardiac catheterization laboratory. The left-sided femoral vessel was used as the access site. How should the nurse position the client?

Supine, with the head of the bed elevated about 15 degrees Following cardiac catheterization, the extremity used for catheter insertion is kept straight for 4 to 6 hours. If the femoral artery was used, strict bed rest is necessary for 6 to 12 hours. The client may turn from side to side. The head of the bed is not elevated more than 15 degrees (unless otherwise prescribed) to prevent kinking of the blood vessel at the groin and possible arterial occlusion.

The nurse is caring for an infant with congenital heart disease. Which, if noted in the infant, should alert the nurse to the early development of heart failure?

The early symptoms of heart failure (HF) include tachypnea, poor feeding, and diaphoresis during feeding. Tachycardia would occur during feeding. Paleness of the skin, pallor, may be noted in the infant with HF, but it is not an early symptom.

The nurse is providing instructions for a client who will collect a stool specimen for an occult blood test. The nurse instructs the client that it is best to avoid which food for 3 days before collection of the stool specimen?

The nurse would instruct the client to avoid red meat, poultry, fish, turnips, horseradish, and foods such as fruits and vegetables for 3 days before and during testing. These foods may alter test results

The nurse is preparing to test a client's blood glucose level with a glucometer. Which steps would facilitate obtaining an accurate result?

When obtaining a droplet of blood for a blood glucose monitor, the site needs to be cleaned with an antiseptic swab and then allowed to dry completely. The puncture site should be the lateral side of the finger because the central tip contains more nerves and may be more painful. Holding the finger in a dependent position improves blood flow to the puncture site. Gentle pressure may be needed to obtain an adequate amount of blood for the test strip.

The nurse is caring for a client with heart failure who is receiving high doses of a diuretic. On assessment, the nurse notes that the client has flat neck veins, generalized muscle weakness, and diminished deep tendon reflexes. The nurse suspects hyponatremia. What additional signs would the nurse expect to note in a client with hyponatremia?

The normal serum sodium level is 135 to 145 mEq/L (135 to 145 mmol/L). Hyponatremia is evidenced by a serum sodium level lower than 135 mEq/L (135 mmol/L). Hyperactive bowel sounds indicate hyponatremia. The remaining options are signs of hypernatremia. In hyponatremia, muscle weakness, increased urinary output, and decreased specific gravity of the urine would be noted.

The nurse is reviewing the laboratory results from a lumbar puncture performed in a client with a diagnosis of meningitis. Which laboratory findings are expected to be noted with bacterial meningitis?

f a bacterial infection of CSF is present, findings include reduced glucose level, an elevated protein level, increased WBCs, a cloudy appearance of CSF, and an elevated CSF pressure.
