Nclex fluid and electrolytes Practice test latest 2024 When caring for a pt diagnosed with hypocalcemia, which of the following should the nurse additionally assess in the pt? 1. other electrolyte disturbances 2. hypertension 3. visual disturbances 4. drug toxicity - Answer: 1 Rationale 1: The pt diagnosed with hypocalcemia may also have high phosphorus or decreased magnesium levels. Rationale 2: The pt with hypocalcemia may exhibit hypotension, & not hypertension. Rationale 3: Visual disturbances do not occur with hypocalcemia. Rationale 4: Hypercalcemia is more commonly caused by drug toxicities. A pt with a history of stomach ulcers is diagnosed with hypophosphatemia. Which of the following interventions should the nurse include in this pt's plan of care? 1. Request a dietitian consult for selecting foods high in phosphorous. 2. Provide aluminum hydroxide antacids as prescribed. 3. Instruct pt to avoid poultry, peanuts, & seeds. 4. Instruct to avoid the intake of sodium phosphate. - Answer: 1 Rationale 1: Treatment of hypophosphatemia includes treating the underlying cause & promoting a high phosphate diet, especially milk, if it is tolerated. Other foods high in phosphate are dried beans & peas, eggs, fish, organ meats, Brazil nuts & peanuts, poultry, seeds & whole grains. Rationale 2: Phosphate-binding antacids, such as aluminum hydroxide, should be avoided. Rationale 3: Poultry, peanuts, & seeds are part of a high phosphate diet. Rationale 4: Mild hypophosphatemia may be corrected by oral supplements, such as sodium phosphate. The nurse is admitting a pt who was diagnosed with acute renal failure. Which of the following electrolytes will be most affected with this disorder? 1. calcium 2. magnesium 3. phosphorous 4. potassium - Answer: 4 Rationale 1: This pt will be less likely to develop a calcium imbalance. Rationale 2: This pt will be less likely to develop a magnesium imbalance. Rationale 3: This pt will be less likely to develop a phosphorous imbalance. Rationale 4: Because the kidneys are the principal organs involved in the elimination of potassium, renal failure A pt is prescribed 40 mEq potassium as a replacement. The nurse realizes that this replacement should be administered 1. directly into the venous access line. 2. mixed in the prescribed intravenous fluid. 3. via a rectal suppository. 4. via intramuscular injection. - Answer: 2 Rationale 1: Never administer undiluted potassium directly into a vein. Rationale 2: The intravenous route is the recommended route for diluted potassium. Rationale 3: The nurse should administer diluted potassium into the pt's intravenous line. Rationale 4: The nurse should administer diluted potassium into the pt's intravenous line. A pt is admitted for treatment of hypercalcemia. The nurse realizes that this pt's intravenous fluids will most likely be which of the following? 1. dextrose 5% & water 2. dextrose 5% & ? normal saline 3. dextrose 5% & ? normal saline 4. normal saline - Answer: 4 Rationale 1: If isotonic saline is not used, the pt is at risk for hyponatremia in addition to the hypercalcemia. Rationale 2: This solution is hypotonic. Isotonic saline is used because sodium excretion is accompanied by calcium excretion through the kidneys. Rationale 3: This solution is hypotonic. Isotonic saline is used because sodium excretion is accompanied by calcium excretion through the kidneys. Rationale 4: Isotonic saline is used because sodium excretion is accompanied by calcium excretion through the kidneys. An elderly pt with peripheral neuropathy has been taking magnesium supplements. The nurse realizes that which of the following symptoms can indicate hypermagnesemia? 1. hypotension, warmth, & sweating 2. nausea & vomiting 3. hyperreflexia 4. excessive urination - Answer: 1 Rationale 1: Elevations in magnesium levels are accompanied by hypotension, warmth, & sweating. Rationale 2: Lower levels of magnesium are associated with nausea & vomiting. Rationale 3: Lower levels of magnesium are associated & hyperreflexia. Rationale 4: Urinary changes are not noted.
