MT The nurse is admitting an older adult with decompensated congestive heart failure. The nursing assessment reveals adventitious lung sounds, dyspnea, and orthopnea. Which physician order should the nurse question?

• Intravenous (IV) 500 mL of 0.9% NaCl at 125 mL/hr
• Furosemide (Lasix) 20 mg PO now
• Oxygen via face mask at 8 L/min
• KCl 20 mEq PO two times per day
• Intravenous (IV) 500 mL of 0.9% NaCl at 125 mL/hr

The nurse assessed four patients at the beginning of the shift. Which finding should the nurse report immediately to the physician?

• Swollen ankles in patient with compensated heart failure
• Positive Chvostek sign in patient with acute pancreatitis
• Dry mucous membranes in patient taking a new diuretic
• Constipation in patient who has advanced breast cancer
• Positive Chvostek sign in patient with acute pancreatitis

The nurse is assessing a patient before hanging an IV solution of 0.9% NaCl with KCl in it.Which assessment finding should cause the nurse to hold the IV solution and contact the physician?

• Weight gain of 2 pounds since last week
• Dry mucous membranes and skin tenting
• Urine output 8 mL/hr
• Blood pressure 98/58
• Urine output 8 mL/hr

At change-of-shift report, the nurse learns the medical diagnoses for four patients. Which patient should the nurse assess most carefully for development of hyponatremia?

• Vomiting all day and not replacing any fluid
• Tumor that secretes excessive antidiuretic hormone (ADH)
• Tumor that secretes excessive aldosterone
• Tumor that destroyed the posterior pituitary gland
• Tumor that secretes excessive

The patient is receiving tube feedings due to a jaw surgery. What change in assessment findings should prompt the nurse to request an order for serum sodium concentration?

• Development of ankle or sacral edema
• Increased skin tenting and dry mouth
• Postural hypotension and tachycardia
• Decreased level of consciousness
• Decreased level of consciousness

The patient with which diagnosis should have the highest priority for teaching regarding foods that are high in magnesium?

• Severe hemorrhage
• Diabetes insipidus
• Oliguric renal disease
• Adrenal insufficiency
• Oliguric renal disease

The patient's laboratory report today indicates severe hypokalemia, and the nurse has notified the physician. Nursing assessment indicates that heart rhythm is regular. What is the priority nursing intervention?

• Raise bed side rails due to potential decreased level of consciousness and

confusion.

• Examine sacral area and patient's heels for skin breakdown due to potential edema.
• Establish seizure precautions due to potential muscle twitching, cramps, and

seizures.

• Institute fall precautions due to potential postural hypotension and weak leg

muscles.

• Institute fall precautions due to potential postural hypotension and weak leg

muscles.

The home health nurse is caring for a patient with a diagnosis of acute immunodeficiency syndrome (AIDS) who has chronic diarrhea. Which assessments should the nurse use to detect the fluid and electrolyte imbalances for which the patient has highest risk? (Select all that apply.)

• Bilateral ankle edema
• Weaker leg muscles than usual
• Postural blood pressure and heart rate
• Positive Trousseau sign
• Flat neck veins when upright
• Decreased patellar reflexes
• Weaker leg muscles than usual
• Postural blood pressure and heart rate
• Positive Trousseau sign

The patient has recent bilateral, above-the-knee amputations and has developed C. difficile diarrhea. What assessments should the nurse use to detect ECV deficit in this patient?(Select all that apply.)

• Test for skin tenting.
• Measure rate and character of pulse.
• Measure postural blood pressure and heart rate.
• Check Trousseau sign.
• Observe for flatness of neck veins when upright.
• Observe for flatness of neck veins when supine.
• Test for skin tenting.
• Measure rate and character of pulse.
• Observe for flatness of neck veins when supine.
• When an excess of body fluid exists in the intravascular compartment, all of the following signs can be expected except:
• Rales
• A bounding pulse
• Engorged peripheral veins
• An elevated hematocrit level
• An elevated hematocrit level

A homeless client is brought into the emergency department with indications of extremely poor nutrition. Arterial blood gas levels are assessed, and the nurse anticipates that this client will demonstrate which of the following results?

• pH 7.3, PaCO2 38 mm Hg, HCO3 19 mEq/L
• pH 7.5, PaCO2 34 mm Hg, HCO3 20 mEq/L
• pH 7.35, PaCO2 35 mm Hg, HCO3 24 mEq/L
• pH 7.52, PaCO2 48 mm Hg, HCO3 28 mEq/
• pH 7.3, PaCO2 38 mm Hg, HCO3 19 mEq/L

When a client's serum sodium level is 120 mEq/L, the priority nursing assessment is to monitor the status of which body system?

• Neurological
• Gastrointestinal
• Pulmonary
• Hepatic
• Neurological

An 8-year-old is admitted to the pediatric unit with pneumonia. On assessment the nurse notes that the child is warm and flushed, is lethargic, has difficulty breathing, and has moist rales. The nurse determines that the child is suffering from:

• Metabolic acidosis
• Respiratory acidosis
• Respiratory alkalosis
• Metabolic alkalosis
• Respiratory acidosis

Arterial blood gas levels are obtained for the client. If the client's results are pH 7.48, CO2 42 mm Hg, and HCO3 32 mEq/L, the client is exhibiting which one of the following acid-base imbalances?

• Metabolic acidosis
• Respiratory acidosis
• Respiratory alkalosis
• Metabolic alkalosis
• Metabolic alkalosis

The nurse is aware that the compensating mechanism that is most likely to occur in the presence of respiratory acidosis is:

• Hyperventilation to decrease the CO2 levels
• Hypoventilation to increase the CO2 levels
• Retention of HCO3 by the kidneys to increase the pH level
• Excretion of HCO3 by the kidneys to decrease the pH level
• Retention of HCO3 by the kidneys to increase the pH level

Of all of the following clients, the nurse recognizes that the individual who is most at risk for a fluid volume deficit is:

• A 6-month-old learning to drink from a cup
• A 12-year-old who is moderately active in 80° F weather
• A 42-year-old with severe diarrhea
• A 90-year-old with frequent headaches
• A 42-year-old with severe diarrhea

• Dextrose 5% in 1/2 NS
