Question 1 of 5
When assessing a patient who is receiving a loop diuretic, the nurse looks for the manifestations of potassium deficiency, which would include what symptoms? (Select all that apply.)
Correct Answer: D
Rationale: Loop diuretics can cause excessive potassium excretion in the urine, leading to low potassium levels in the body (hypokalemia). Some manifestations of potassium deficiency (hypokalemia) include muscle weakness, which can range from mild to severe, and anorexia (loss of appetite). Other symptoms of hypokalemia may include fatigue, weakness, constipation, and even cardiac arrhythmias. It is important for healthcare providers to monitor patients on loop diuretics for signs of potassium deficiency to prevent complications.
Question 2 of 5
The nurse is reviewing the care plan with a patient using enteral nutrition (EN). Which interventions by the nurse are appropriate for this strategy? (Select all that apply.)
Correct Answer: A
Rationale: Checking gastric residuals (A) ensures proper gastric emptying and reduces aspiration risk. Elevating the bed (B) prevents reflux and aspiration. Reporting absent bowel sounds (D) is critical, as EN is contraindicated in ileus. Feeding bags and tubing should be changed every 24 hours, not 3 to 4 days (C).

Some manifestations of potassium deficiency (hypokalemia) include muscle weakness, which can range from mild to severe, and anorexia (loss of appetite).

Question 4 of 5
Penicillin G has been prescribed for a patient. Which nursing intervention(s) should the nurse perform for this patient? (Select all that apply.)
Correct Answer: A
Rationale: Penicillin G is a beta-lactam antibiotic that can cause severe allergic reactions, including anaphylaxis. Having epinephrine on hand is crucial for managing such emergencies. Collecting a culture and sensitivity before the first dose ensures the infection is caused by a penicillin-susceptible organism. Mouth ulcers are not a common side effect of penicillin, but monitoring for superinfections like oral thrush is important. Limiting fluid intake to 1000 mL/day is incorrect, as adequate hydration helps maintain renal function and prevents crystalluria. No particular interventions are required is incorrect, as penicillin requires careful monitoring for efficacy and adverse effects.
Question 5 of 5
The ability of epinephrine to cause hyperglycemia is due to;
Correct Answer: C
Rationale: The ability of epinephrine to cause hyperglycemia is primarily due to its effect on alpha adrenoreceptors in the pancreatic islets of Langerhans. Epinephrine, acting through these alpha adrenoreceptors, inhibits the release of insulin from beta cells in response to elevated blood glucose levels. This results in decreased uptake of glucose by cells, leading to increased blood glucose levels, ultimately causing hyperglycemia. Other effects of epinephrine, such as vasoconstriction and increased heart rate, also contribute to the overall stress response, but the inhibition of insulin release through alpha adrenoreceptors is the main mechanism responsible for its hyperglycemic effects.
