HESI RN CAT Exam Quizlet
1. The nurse is assessing on the first postoperative day following thyroid surgery. Which laboratory value is most important for the nurse to monitor?
- A. Calcium
- B. Sodium
- C. Chloride
- D. Potassium
Correct answer: A
Rationale: Corrected Rationale: Monitoring calcium levels is crucial post-thyroid surgery to detect hypocalcemia, a common complication due to injury or removal of the parathyroid glands. Monitoring sodium, chloride, or potassium levels is not as vital in the immediate post-thyroid surgery period.
2. A client with a history of peptic ulcer disease (PUD) is admitted after vomiting bright red blood several times over the course of 2 hours. In reviewing the laboratory results, the nurse finds the client's hemoglobin is 12 g/dL (120g/L) and the hematocrit is 35% (0.35). Which action should the nurse prepare to take?
- A. Continue monitoring for blood loss
- B. Administer 1,000 mL (1L) of normal saline
- C. Transfuse 2 units of platelets
- D. Prepare the client for emergency surgery
Correct answer: D
Rationale: The correct answer is to prepare the client for emergency surgery. The client's presentation with bright red blood in vomitus suggests active bleeding, which is a medical emergency. With a hemoglobin of 12 g/dL and a hematocrit of 35%, the client is likely experiencing significant blood loss that may require surgical intervention to address the source of bleeding. Continuing to monitor for blood loss (Choice A) is not appropriate in this acute situation where immediate action is necessary. Administering normal saline (Choice B) may help with fluid resuscitation but does not address the underlying cause of bleeding. Transfusing platelets (Choice C) is not indicated in this scenario as platelets are involved in clot formation and are not the primary treatment for active bleeding in this context.
3. A child with Graves' disease who is taking propranolol (Inderal) is seen in the clinic. The nurse should monitor the child for which therapeutic response?
- A. Increased weight gain
- B. Decreased heart rate
- C. Reduced headaches
- D. Diminished fatigue
Correct answer: B
Rationale: When a child with Graves' disease is prescribed propranolol (Inderal), the nurse should monitor for a decreased heart rate as a therapeutic response. Propranolol is a beta-blocker that acts to slow down the heart rate, which is beneficial in managing the symptoms of Graves' disease, such as tachycardia and other cardiovascular manifestations. Choices A, C, and D are incorrect because propranolol is not typically associated with increased weight gain, reduced headaches, or diminished fatigue as its primary therapeutic effect in this context.
4. A client is being prepared for a colonoscopy. Into which position does the nurse assist the client for the procedure?
- A. Left Sims' position
- B. Lithotomy position
- C. Knee-chest position
- D. Right Sims' position
Correct answer: A
Rationale: During a colonoscopy, the client is positioned in the left Sims' position. This position is chosen as it optimally utilizes the client’s anatomy to facilitate the introduction of the colonoscope. The lithotomy position (Choice B) is commonly used for gynecological exams, not colonoscopies. The knee-chest position (Choice C) is typically employed for rectal examinations or certain surgical procedures, not colonoscopies. The right Sims' position (Choice D) is a less common position for colonoscopy compared to the left Sims' position.
5. What is considered the main objective of the translation stage of protein synthesis?
- A. To produce amino acids
- B. To produce nucleotides
- C. To produce fatty acids
- D. To produce nucleic acids
Correct answer: A
Rationale: The correct answer is A: To produce amino acids. During the translation stage of protein synthesis, the mRNA is decoded to assemble a specific sequence of amino acids. These amino acids then fold into a functional protein. Choices B, C, and D are incorrect because the translation stage specifically deals with the production of amino acids, not nucleotides, fatty acids, or nucleic acids.
