HESI RN Exit Exam 2023 Capstone
1. A client is admitted with diabetic ketoacidosis (DKA). Which laboratory result would the nurse expect to find in this client?
- A. pH level of 7.45
- B. Serum calcium of 15 mg/dL
- C. Blood glucose of 450 mg/dL
- D. Sodium level of 120 mEq/L
Correct answer: C
Rationale: Clients with diabetic ketoacidosis typically present with elevated blood glucose levels, often above 300 mg/dL. This high blood glucose level, along with other symptoms, helps confirm the diagnosis of DKA. A pH level of 7.45 would be indicative of alkalosis, not the acidosis seen in DKA. A serum calcium level of 15 mg/dL is significantly elevated and is not a typical finding in DKA. A sodium level of 120 mEq/L indicates hyponatremia, which is not a characteristic laboratory finding in DKA.
2. A client with renal insufficiency and a low red blood cell count asks, 'Is my anemia related to the renal insufficiency?' How should the nurse respond?
- A. Red blood cells produce erythropoietin, which increases blood flow to the kidneys.
- B. Your anemia and renal insufficiency are related to inadequate vitamin D and a loss of bone density.
- C. Erythropoietin is usually released from the kidneys and stimulates red blood cell production in the bone marrow.
- D. Kidney insufficiency inhibits active transportation of red blood cells throughout the blood.
Correct answer: C
Rationale: The correct answer is C. Erythropoietin is produced in the kidney and is released in response to decreased oxygen tension in the renal blood supply. Erythropoietin stimulates red blood cell production in the bone marrow. Anemia in renal insufficiency is often due to decreased erythropoietin production. Anemia and renal insufficiency are not manifestations of vitamin D deficiency as stated in choice B. Choice A is incorrect as erythropoietin does not increase blood flow to the kidneys. Choice D is incorrect because kidney insufficiency does not inhibit active transportation of red blood cells throughout the blood; rather, it affects erythropoietin production and subsequent red blood cell formation.
3. A client is prescribed an inhaled corticosteroid for asthma management. Which instruction should the nurse provide to the client regarding the use of this medication?
- A. Rinse your mouth after using the inhaler
- B. Hold your breath for 5 seconds after inhaling the medication
- C. Use the inhaler during an acute asthma attack
- D. Take the medication only when symptoms occur
Correct answer: A
Rationale: The correct instruction for a client using an inhaled corticosteroid for asthma management is to rinse the mouth after using the inhaler. This helps prevent oral thrush, a common side effect of corticosteroid inhalers. Holding the breath for 5 seconds after inhaling the medication (Choice B) is not necessary for corticosteroid inhalers. Using the inhaler during an acute asthma attack (Choice C) is not the purpose of corticosteroids, which are used for long-term asthma management. Taking the medication only when symptoms occur (Choice D) is not correct as corticosteroids are typically used regularly to control asthma symptoms.
4. Angiotensin-converting enzyme (ACE) inhibitors may be prescribed for the client with diabetes mellitus to reduce vascular changes and possibly prevent or delay the development of:
- A. Chronic obstructive pulmonary disease (COPD).
- B. Pancreatic cancer.
- C. Renal failure.
- D. Cerebrovascular accident.
Correct answer: C
Rationale: The correct answer is C: Renal failure. ACE inhibitors are commonly used in clients with diabetes mellitus to help reduce the progression of diabetic nephropathy by improving renal blood flow. This medication class can help prevent or delay the development of renal failure in these clients. Choices A, B, and D are incorrect because ACE inhibitors do not have a direct impact on preventing or delaying the development of chronic obstructive pulmonary disease, pancreatic cancer, or cerebrovascular accidents in clients with diabetes mellitus.
5. During an examination for possible cryptorchidism in an infant, what technique should be used?
- A. Place the infant in a warm room and use a calm approach.
- B. Hold the scrotum and palpate gently.
- C. Cleanse the penis with an antiseptic-soaked pad.
- D. Position the infant in a warm room to prevent muscle contraction.
Correct answer: D
Rationale: When examining an infant for cryptorchidism, it is important to position the infant in a warm room to prevent muscle contraction, which could cause the testes to retract. Placing the infant in a side-lying position may not be necessary for this specific examination. Holding the penis or retracting the foreskin is not relevant to the assessment for cryptorchidism. Cleansing the penis with an antiseptic pad is not indicated for this examination.
