A. Hypokalemia Deficiency of potassium in the bloodstream Flattened T waves, Peaked P waves

An Electrocardiogram ECG is performed before a client is to have a cardiac catheterization, and hypokalemia a suspected. What does the nurse expect the primary healthcare provider to prescribe to confirm the presence of hypokalemia? A. A Complete blood count B. A serum electrolyte level C. An arterial blood gas panel D. An x-ray film of long bones

B. A serum electrolyte level Serum electrolyte level will tell us if the potassium level is low

Administering serum albumin intravenously to a client with ascites. In response to this therapy, what does the nurse expect to decrease? A. Confusion B. Urinary output capital C. Abdominal girth D. Serum ammonia level

C. Abdominal girth Ascites- fluid in the abdomen Serum albumin pulls fluid back into the intravascular compartment

Induced hormonal imbalance is likely to be observed in the client undergoing treatment with demeclocycline? A. Acromegaly B. Diabetes mellitus C. Diabetes insipidus D. Cushing's syndrome

C. Diabetes insipidus

The nurse suspects that a client with inhalation anthrax is in the fulminant stage of the disease. Which symptom supports the nurses conclusion? A. Fever B. Dry cough C. Hematemesis D. Mild chest pain

C. Hematemesis Vomiting blood

Which hormonal deficiency causes diabetes insipidus in a client? A. Prolactin B. Thyrotropin C. Luteinizing hormone (LH) D. Antidiuretic hormone (ADH)

D. Antidiuretic hormone (ADH)

The serum ammonia level of a client with hepatic cirrhosis and ascites is elevated. What nursing intervention is the priority? A. Weigh the client daily B. Restrict the clients oral fluid intake C. Measure the clients urine specific gravity D. Observe the client for increasing confusion

D. Observe the client for increasing confusion Increased serum ammonia level impairs the central nervous system

Which laboratory value may indicate hyperfunction of the adrenal gland in a client? A. Sodium: 143 mEq/L B. Potassium: 2.9 mEq/L C. Bicarbonate: 25 mEq/L D. Total calcium: 10 mg/dL

B. Potassium: 2.9 mEq/L normal levels of potassium: 3.5-5.0 mEq/L

A nurse is caring for an older adult who was admitted to the hospital to be treated for dehydration. While the nurse is providing discharge teaching, the client asked what to do about itchy dry skin? What is the best response by the nurse? A. Wear plenty of warm clothes to keep moisture in the skin B. Use moisturizer on the skin daily to reduce itching C. Take hot tub baths only twice a week to reduce drying of the skin D. Expose the skin to the air to help reduce the sensation of itching.

B. Use moisturizer on the skin daily to reduce itching

A client is receiving furosemide to relieve edema. The nurse should monitor the client for which response to the medication? A. Hypernatremia B. Low blood urea nitrogen C. Hypokalemia D. Increase in the urine specific gravity

C. Hypokalemia furosemide causes depletion of electrolytes such as potassium and sodium

What dose the nurse identify as priority short term goal for toddler with dehydration caused by diarrhea? A. Improvement of fluid balance B. Continuation of an antidiarrheal diet C. preservation of perianal skin integrity D. Retention of weight appropriate for height

A. Improvement of fluid balance

A nurse administers a parenteral preparation of potassium slowly and cautiously to avoid which complication? A. Acidosis B. Cardiac arrest C. Psychoticlike reaction D. Edema of extremities

B. Cardiac arrest Too rapid administration can cause hyperkalemia, which can lead to cardiac arrest

A Client is receiving furosemide to help treat heart failure. Which laboratory results will cause the nurse to notify the primary healthcare provider? A. Hematocrit 46% B. Hemoglobin 14.1 g/dL C. Potassium 3.0 mEq/L D. White blood cell 9200/mm3

C. Potassium 3.0 mEq/L Normal levels range 3.5-5.0 mEq/L

The nurse is teaching a client receiving peritoneal dialysis about the reason dialysis solution is warmed before it is instilled into the peritoneal cavity. Which information will the nurse share with a client? A. Because it forces potassium back into the cells, thereby decreasing serum levels B. Because it adds extra warmth to the body because metabolic processes are disturbed C. Because it helps prevent cardiac dysrhythmias by speeding up removal of excess potassium D. Because it encourages removal of serum urea by preventing constriction of peritoneal blood vessels

D. Because it encourages removal of serum urea by preventing constriction of peritoneal blood vessels

At 10 AM the nurse hangs a 1000 mL bag of D5W with 20 mEq of potassium chloride to administer at 80 mL per hour. At noon the healthcare provider prescribes a stat infusion of an intravenous IV antibiotic of 100 mL to be administered via piggyback over one hour. How much longer than expected will it take the primary bag to empty if the nurse interrupts the primary infusion to use the circulatory access for the secondary infusion of the antibiotic? A. Quarter hour B. Half hour C. Three quarters of an hour D. 1 hour

D. 1 hour An infusion of 1000 mL at 80 mL should take 12.5 hours. Because the primary infusion is interrupted for an hour while the antibiotic is infused, the primary bad will take an extra hour.
