Nursing practice questions with comprehensive rationales
NurseDive Free Nursing Practice Question
A patient with chronic renal failure has an occluded arteriovenous fistula, and routine hemodialysis is delayed. However, the patient's serum potassium level is 6.0 mEq/L. What should the nurse expect to be prescribed for this patient? Select all that apply.
A. Sodium bicarbonate.
The administration of sodium bicarbonate helps to correct acidosis, which can occur in chronic renal failure due to the accumulation of metabolic waste products in the absence of effective kidney function.
B. Dextrose 10%.
-
C. Sodium polystyrene sulfonate (Kayexalate).
Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia, which is common in chronic renal failure due to impaired potassium excretion by the kidneys.
D. Insulin.
Insulin can be prescribed to treat hyperkalemia by promoting the uptake of potassium into cells, thereby reducing the serum potassium level. Choice B and E rationale: Dextrose 10% and furosemide (Lasix) are not appropriate treatments for hyperkalemia. Dextrose 10% is asugar solution and does not impact potassium levels, while furosemide is a loop diuretic that primarily affects sodium and water excretion, not potassium.

A, C, and D.
Choice A rationale:

Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia, which is common in chronic renal failure due to impaired potassium excretion by the kidneys.
Choice D rationale:
Insulin can be prescribed to treat hyperkalemia by promoting the uptake of potassium into cells, thereby reducing the serum potassium level. Choice B and E rationale: Dextrose 10% and furosemide (Lasix) are not appropriate treatments for hyperkalemia. Dextrose 10% is a sugar solution and does not impact potassium levels, while furosemide is a loop diuretic that primarily affects sodium and water excretion, not potassium.

A patient experiencing multisystem fluid volume deficit has tachycardia, pale, cool skin, and decreased urine output. The nurse realizes these findings are most likely a direct result of which process?
A. Effects of rapidly infused intravenous fluids.
Effects of rapidly infused intravenous fluids are not the cause of the patient's current findings. In fact, the nurse's notes indicate that the IV fluid therapy (0.9% sodium chloride) was initiated at 125 mL/hr, which is a relatively standard and cautious rate. Rapidly infused fluids could potentially cause fluid overload, but that is not the situation here.
B. The body's natural compensatory mechanisms.
The patient's tachycardia, pale, cool skin, and decreased urine output are signs of the body's natural compensatory mechanisms in response to fluid volume deficit. When the body experiences a decrease in fluid volume, it tries to compensate by increasing heart rate (tachycardia) to maintain blood flow to vital organs and constricting blood vessels to preserve fluid and maintain blood pressure. Pale, cool skin is a result of vasoconstriction, and decreased urine output is a way the body conserves water during dehydration.
C. Pharmacological effects of a diuretic.
Pharmacological effects of a diuretic are not relevant to this patient's presentation. There is no mention of diuretic use in the nurse's notes, and the symptoms presented are more consistent with fluid volume deficit and dehydration rather than diuretic use.
D. Cardiac failure.
Cardiac failure is not the correct answer, as there is no indication of heart failure in the patient's presentation or nurse's notes. The symptoms and findings described are more indicative of fluid volume deficit, which is not synonymous with cardiac failure.

A nurse is teaching a client who is on a low-sodium diet. Which of the following instructions should the nurse include? (Select All that Apply.).
A. Limit intake of canned soups.
Canned soups often contain high levels of sodium, which can contribute to exceeding the recommended daily sodium intake. Limiting these can help manage sodium levels effectively.
B. Choose diet sodas over bottled water.
Choosing diet sodas over bottled water is not advisable. Diet sodas can still contain sodium and other additives that are not beneficial for a low-sodium diet. Bottled water is a better choice as it typically contains no sodium.
C. Choose bottled salad dressings.
Bottled salad dressings often contain high amounts of sodium. Opting for homemade or low-sodium versions is a better strategy for maintaining a low-sodium diet.
D. Read labels on foods before eating.
Reading labels on foods before eating is crucial for identifying hidden sources of sodium and making informed dietary choices. This practice helps in adhering to a low-sodium diet by avoiding foods with high sodium content.

A nurse is caring for a client who has a urinary tract infection.
Drag words from the choices below to fill in each blank in the following sentence.
The client is at an increased risk for developing
Full Explanation
Choice A rationale:
Target conditions are not mentioned in the sentence, and there is no context to suggest their relevance to the client's situation.
Choice B rationale:
Hyperactive reflexes are not commonly associated with a urinary tract infection or the prescribed medications.
Choice C rationale:
The client with a urinary tract infection and the medications mentioned (Furosemide and Trimethoprim/sulfamethoxazole) are at an increased risk of hypokalemia (low potassium levels) due to Furosemide's diuretic effect, fluid volume deficit (dehydration) from the infection, and hypertension (high blood pressure) as a potential side effect of Trimethoprim/sulfamethoxazole.
Choice D rationale:
Urinary retention is not expected in a client with a urinary tract infection; it is more commonly associated with urinary obstruction or other urinary conditions unrelated to an infection.
