A client at risk for mild hypernatremia is being taught by a nurse. Which statement should the nurse include in this client's teaching?
- A. Weigh yourself every morning and every night
- B. Check your radial pulse twice a day
- C. Read food labels to determine sodium content
- D. Bake or grill the meat rather than frying it
Correct Answer: C
Rationale: The correct answer is C. Reading food labels to determine sodium content is important in managing mild hypernatremia. This allows the client to monitor and control their sodium intake, which can help prevent further elevation of sodium levels. Weighing oneself or checking the pulse does not directly address sodium intake. Choosing cooking methods like baking or grilling is more about reducing fat intake, not sodium.

A nurse is caring for a client who is experiencing excessive diarrhea. The clients arterial blood gas values are pH 7.28, PaO2 98 mm Hg, PaCO2 45 mm Hg, and HCO3 16 mEq/L. Which provider order should the nurse expect to receive?
- A. Furosemide (Lasix) 40 mg intravenous push
- B. Sodium bicarbonate 100 mEq diluted in 1 L of D5W
- C. Mechanical ventilation
- D. Indwelling urinary catheter
Correct Answer: B
Rationale: The correct answer is B: Sodium bicarbonate 100 mEq diluted in 1 L of D5W. In this case, the client is experiencing metabolic acidosis due to low HCO3 levels (16 mEq/L) with a low pH (7.28). Sodium bicarbonate helps correct metabolic acidosis by increasing the HCO3 levels. Furosemide (A) is a diuretic and can worsen the client's electrolyte imbalance. Mechanical ventilation (C) is not indicated for metabolic acidosis. Indwelling urinary catheter (D) does not address the underlying acid-base imbalance. Therefore, the nurse should expect the provider to order sodium bicarbonate to correct the metabolic acidosis.
The nurse caring for a patient post colon resection is assessing the patient on the second postoperative day. The
nasogastric tube (NG) remains patent and continues at low intermittent wall suction. The IV is patent and infusing at
125 mL/hr. The patient reports pain at the incision site rated at a 3 on a 0-to-10 rating scale. During your initial shift
assessment, the patient complains of cramps in her legs and a tingling sensation in her feet. Your assessment indicates
decreased deep tendon reflexes (DTRs) and you suspect the patient has hypokalemia. What other sign or symptom
would you expect this patient to exhibit
- A. Diarrhea
- B. Dilute urine
- C. Increased muscle tone
- D. Joint pain
Correct Answer: B
Rationale: The correct answer is B: Dilute urine. Hypokalemia can lead to kidney dysfunction, causing the kidneys to excrete more water along with electrolytes, resulting in dilute urine. This is a manifestation of the body's attempt to compensate for low potassium levels by excreting excess water. The other choices are incorrect because: A) Diarrhea is more commonly associated with hyperkalemia, not hypokalemia. C) Increased muscle tone is not a typical sign of hypokalemia; rather, hypokalemia can lead to muscle weakness or paralysis due to impaired muscle function. D) Joint pain is not a typical symptom of hypokalemia; joint pain is more commonly associated with other conditions such as arthritis or inflammation.
A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 22 mEq/L. Which client condition should the nurse correlate with these results?
- A. Diarrhea and vomiting for 36 hours
- B. . Anxiety-induced hyperventilation
- C. Chronic obstructive pulmonary disease (COPD)
- D. Diabetic ketoacidosis and emphysema
Correct Answer: B
Rationale: The correct answer is B: Anxiety-induced hyperventilation. The arterial blood gas values show a pH of 7.48 (alkalosis) with low PaCO2 (respiratory alkalosis), which is consistent with hyperventilation due to anxiety. HCO3 is within normal range, ruling out metabolic causes. A: Diarrhea and vomiting would lead to metabolic acidosis with low pH and decreased HCO3. C: COPD would typically present with respiratory acidosis (high PaCO2) and normal to high HCO3. D: Diabetic ketoacidosis and emphysema would show metabolic acidosis with low pH and low HCO3.
A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?
- A. A 34-year-old on NPO status who is receiving intravenous D5W
- B. A 50-year-old with an infection who is prescribed a sulfonamide antibiotic
- C. A 67-year-old who is experiencing pain and is prescribed ibuprofen (Motrin)
- D. A 73-year-old with tachycardia who is receiving digoxin (Lanoxin)
Correct Answer: A
Rationale: The correct answer is A because intravenous D5W is a hypotonic solution that can lead to dilutional hyponatremia. D5W does not contain sodium, so it can cause a decrease in serum sodium levels. Clients on NPO status receiving D5W are at higher risk due to lack of sodium intake. Choices B, C, and D are incorrect because they do not directly contribute to hyponatremia. Sulfonamide antibiotics, ibuprofen, and digoxin are not typically associated with causing hyponatremia. Therefore, assessing the client on NPO status receiving D5W for potential hyponatremia is the priority.
A nurse is planning care for a client who is hyperventilating. The clients arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3 26 mEq/L. Which question should the nurse ask when developing this clients plan of care?
- A. Do you take any over-the-counter medications?
- B. You appear anxious. What is causing your distress?
- C. Do you have a history of anxiety attacks?
- D. You are breathing fast. Is this causing you to feel light-headed?
Correct Answer: B
Rationale: The correct answer is B: "You appear anxious. What is causing your distress?" because hyperventilation can be triggered by emotional distress or anxiety. By addressing the underlying cause of the hyperventilation, the nurse can provide appropriate interventions to help the client manage their anxiety and subsequently reduce the hyperventilation episodes.
A: "Do you take any over-the-counter medications?" - This question is not directly related to addressing the client's anxiety or distress, which is the primary concern in hyperventilation.
C: "Do you have a history of anxiety attacks?" - While relevant to understanding the client's medical history, this question does not address the immediate cause of hyperventilation in this specific situation.
D: "You are breathing fast. Is this causing you to feel light-headed?" - This question focuses on the physical symptoms of hyperventilation rather than exploring the emotional or psychological triggers, which are essential in managing hyperventilation caused by anxiety.
