The oncoming nurse is assigned to the following clients. Which client should the nurse assess first?

a newly admitted 88-year-old with a 2-day history of vomiting and loose stools

The nurse is providing care to a client who has been experiencing emesis (vomiting) for 24 hours. Which fluid should the nurse anticipate incorporating into the client's plan of care?

hypotonic Rationale: A hypotonic solution contains fewer dissolved substances than normally found in plasma. It is administered to clients with fluid losses in excess of fluid intake, such as those who have diarrhea or vomiting. The other fluids are not appropriate to administer.

Banana Rationale: Bananas are high in potassium and would place the client receiving a potassium-sparing diuretic at risk for increased potassium levels. Milk and yogurt are good sources of calcium and phosphorus and would not be a concern. Turkey provides protein and would not be problematic.

Assessment of a client reveals the following findings: elevated body temperature, dry skin, low urinary output, and increased pulse rate. The client's health record indicates that he is taking diuretics. Which nursing diagnosis would be most appropriate for the client?

ECF Deficient Fluid Volume

A nurse is providing care to a client who has been vomiting for the past 2 days. The nurse would assess this client for which imbalance? Select all that apply.

Hypokalemia & Metabolic alkalosis Rationale: If sufficient gastric juice (ECF with additional acid) is lost from the stomach, then consequently hydrogen, sodium, and chloride ions are depleted, increasing the risk of ECF volume deficit and/or metabolic alkalosis. Gastric fluid also is high in potassium, and excessive losses may contribute to hypokalemia. Respiratory acidosis would be more likely to occur with an underlying lung disorder, such as asthma or emphysema. Vomiting leads to a loss of sodium, so elevated sodium levels would be unlikely. Imbalances of calcium are not typically associated with imbalances associated with vomiting.

A client has been receiving intravenous (IV) fluids that contain potassium. The IV site is red and there is a red streak along the vein that is painful to the client. What is the priority nursing action?

Remove the IV Rationale: The client likely has phlebitis, which is caused by prolonged use of the same vein or irritating fluid. Potassium is known to be irritating to the veins. The priority action is to remove the IV and restart another IV using a different vein. The other actions are appropriate, but should occur after the IV is removed.

The nurse is performing an assessment of a client with hypocalcemia who has been admitted to the acute care facility. Which symptom does the nurse document that correlates with the admitting diagnosis?

Report of muscle cramps Report of numbness and tingling of the mouth Seizure activity Blood clotting Rationale: Calcium is important in wound healing, synaptic transmission in nervous tissue, membrane excitability, and is essential for blood clotting. Manifestations of hypocalcemia include numbness and tingling of fingers, mouth, or feet; tetany; muscle cramps; and seizures. Slurred speech and reports of excessive urination are indicative of hypercalcemia.

cardiac irregularities

A nurse who has diagnosed a client as having "fluid volume excess" related to compromised regulatory mechanism (kidneys) may have been alerted by what symptom?

distended neck veins

Endurance athletes who exercise for long periods of time and consume only water may experience a sodium deficit in their extracellular fluid. This electrolyte imbalance is known as:

hyponatremia Hyponatremia refers to a sodium deficit in the extracellular fluid caused by a loss of sodium or a gain of water. Hypernatremia refers to a surplus of sodium in the ECF. Hypokalemia refers to a potassium deficit in the ECF. Hyperkalemia refers to a potassium surplus in the ECF.

The nurse is caring for a client whose baseline weight is 125 lb (56.7 kg). The client weighs 115 lb (52.2 kg) today. How does the nurse document the client's status?

moderately dehydrated Rationale: Hypovolemia refers to a low volume of extracellular fluid. If untreated, it may result in dehydration. Mild dehydration is present when there is a 3% to 5% loss of body weight Moderate dehydration is associated with a 6% to 10% loss of body weight Severe dehydration, a life-threatening emergency, occurs with a loss of more than 9% to 15% of body weight. This client has lost 8% of body weight (10 pounds), and is therefore moderately dehydrated.

Which explanations from the student about fluid and electrolyte balance demonstrate that learning has taken place regarding the function of water? Select all that apply.

provides a medium for transporting substances throughout the body facilitates cellular metabolism and proper cellular chemical functioning helps maintain normal body temperature facilitates digestion and promotes elimination

The nurse is monitoring intake and output (I&O) for a client who recently had surgery. Which client actions will the nurse document on the I&O record? Select all that apply.

infusion of intravenous solution urination vomiting drinking milk Rationale: Ingested solids, such as a sandwich, are not included in the intake and output.

Based on knowledge of total body fluids, a nurse is especially watchful for a fluid volume deficit in an infant. Why would the nurse do this?

Infants have more total body fluid and ECF than adults.

renal failure

What is the body mass index (BMI) of a client who is 1.68 meters tall and weighs 70 kg?

24.8

A nursing student is teaching a healthy adult client about adequate hydration. Which statement by the client indicates understanding of adequate hydration?

"I should drink 2,500 mL/day of fluid." Rationale: In healthy adults, fluid intake generally averages approximately 2,500 mL/day, but it can range from 1,800 to 3,000 mL/day with a similar volume of fluid loss.

Which nursing diagnosis would the nurse make based on the effects of fluid and electrolyte imbalance on human functioning?

Acute Confusion related to cerebral edema

A health care provider writes a prescription to "force fluids." What will be the first action the nurse will take in implementing this prescription?

Explain to the client why this is needed.

The nurse is caring for a male client who has a diagnosis of heart failure. Today's laboratory results show a serum potassium of 3.2 mEq/L (3,2 mmol/L). For what complications should the nurse be aware, related to the potassium level?

Cardiac dysrhythmias Rationale: Typical signs of hypokalemia include muscle weakness and leg cramps, fatigue, paresthesias, and dysrhythmias. Pulmonary emboli and fluid volume excess are not related to a low potassium level. Tetany can be a result of low calcium or high phosphorus but is not related to potassium levels.

A client is admitted to the facility after experiencing uncontrolled diarrhea for the past several days. The client is exhibiting signs of a fluid volume deficit. When reviewing the client's laboratory test results, which electrolyte imbalance would the nurse most likely find?

Hypokalemia

A nurse is reviewing the client's serum electrolyte levels which are as follows:Sodium: 138 mEq/L (138 mmol/L)Potassium: 3.2 mEq/L (3.2 mmol/L)Calcium: 10.0 mg/dL (2.5 mmol/L)Magnesium: 2.0 mEq/L (1.0 mmol/L)Chloride: 100 mEq/L (100 mmol/L)Phosphate: 5.75 mg/dL (1.8 mEq/L)Based on these levels, the nurse would identify which imbalance?

Hypokalemia

ICF

A nurse is caring for a client with a gastrostomy tube in place. What is an accurate guideline for care of the insertion site?

If the gastric tube insertion site has healed and the sutures are removed, use soap and water to clean the site.

The nurse is caring for a client whose blood type is A negative. Which donor blood type does the nurse confirm as compatible for this client?

O negative Rationale: Type O blood is considered the universal donor because it lacks both A and B blood group markers on its cell membrane. Therefore, type O blood can be given to anyone because it will not trigger an incompatibility reaction when given to recipients with other blood types. Rh-negative persons should never receive Rh-positive blood.
