Mental Health HESI Quizlet
1. The RN is preparing medications for a client with bipolar disorder and notices that the client discontinued antipsychotic medication for several days. Which medication should also be discontinued?
- A. Lithium (Lithotabs).
- B. Benztropine (Cogentin).
- C. Alprazolam (Xanax).
- D. Magnesium (Milk of Magnesia).
Correct answer: B
Rationale: The correct answer is Benztropine (Cogentin). Benztropine is commonly prescribed to manage side effects of antipsychotic medications. Therefore, if the antipsychotic medication is discontinued, there would be no need for Benztropine. Lithium is a mood stabilizer used in bipolar disorder, not directly related to antipsychotic use. Alprazolam is an anxiolytic, and Magnesium (Milk of Magnesia) is a laxative, neither of which is typically associated with antipsychotic medication use.
2. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?
- A. Decreased blood glucose levels
- B. Decreased urine ketones
- C. Increased serum bicarbonate
- D. Increased anion gap
Correct answer: D
Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.
3. A nurse is assessing a newly admitted patient with chronic heart failure who forgot to take prescribed medications and seems confused. The patient complains of "just blowing up" and has peripheral edema and shortness of breath. Which assessment should the nurse complete first?
- A. Skin turgor
- B. Heart sounds
- C. Mental status
- D. Capillary refill
Correct answer: C
Rationale: Increases in extracellular fluid (ECF) can lead to swelling of cells in the central nervous system, initially causing confusion, which may progress to coma or seizures. Although skin turgor, capillary refill, and heart sounds also may be affected by increases in ECF, these are signs that do not have as immediate impact on patient outcomes as cerebral edema.
4. What is the leading cause of maternal mortality?
- A. Pre-eclampsia
- B. Haemorrhage
- C. Sepsis
- D. Obstructed labour
Correct answer: B
Rationale: The correct answer is B: Haemorrhage. Haemorrhage is a leading cause of maternal mortality due to excessive bleeding during childbirth. While conditions like pre-eclampsia, sepsis, and obstructed labor can also be serious complications during pregnancy and childbirth, they are not the primary cause of maternal mortality worldwide.
5. A client with chronic renal failure is receiving sodium polystyrene sulfonate (Kayexalate). The nurse should monitor the client for which of the following?
- A. Hyponatremia.
- B. Hypokalemia.
- C. Hyperkalemia.
- D. Hypocalcemia.
Correct answer: C
Rationale: Correct Answer: The correct answer is C, 'Hyperkalemia.' Sodium polystyrene sulfonate (Kayexalate) is a medication used to treat high potassium levels (hyperkalemia) by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Therefore, the nurse should monitor the client for changes in potassium levels to assess the effectiveness of the medication and prevent potential complications related to hyperkalemia. Choice A, 'Hyponatremia,' is incorrect as Kayexalate does not primarily affect sodium levels. Choice B, 'Hypokalemia,' is incorrect as Kayexalate is used to treat high potassium levels, not low. Choice D, 'Hypocalcemia,' is incorrect as Kayexalate does not directly impact calcium levels.
