HESI RN CAT Exit Exam 1
1. Which client requires careful nursing assessment for signs and symptoms of hypomagnesaemia?
- A. A young adult client with intractable vomiting due to food poisoning
- B. A client who developed hyperparathyroidism in late adolescence
- C. A middle-aged male client in renal failure following an unsuccessful kidney transplant
- D. A female client who excessively consumes simple carbohydrates
Correct answer: C
Rationale: The correct answer is C. Clients in renal failure are at high risk for hypomagnesemia due to their impaired kidney function. Renal failure can lead to decreased excretion of magnesium, resulting in its buildup in the body and potential hypomagnesemia. This client requires careful nursing assessment for signs and symptoms of hypomagnesemia to prevent complications. Choices A, B, and D are not as directly associated with renal failure and its impact on magnesium levels. Intractable vomiting, hyperparathyroidism, and excessive consumption of simple carbohydrates may have other health implications but are not as strongly linked to hypomagnesemia as renal failure.
2. A nurse is planning care for a client who has a new prescription for metoprolol (Lopressor). Which assessment finding should the nurse report to the healthcare provider before administering the medication?
- A. Heart rate of 50 beats per minute
- B. Blood pressure of 90/60 mm Hg
- C. Respiratory rate of 20 breaths per minute
- D. Temperature of 99°F (37.2°C)
Correct answer: A
Rationale: A heart rate of 50 beats per minute is a concerning finding that should be reported before administering metoprolol. Metoprolol is a beta-blocker that can further lower the heart rate, so a heart rate of 50 bpm indicates potential bradycardia, which is a contraindication for administering this medication. Choices B, C, and D are within normal ranges and do not pose immediate concerns related to metoprolol administration.
3. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2°F and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?
- A. Occult blood in the stool
- B. Abdominal distention
- C. Elevated urine specific gravity
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: Elevated urine specific gravity is a sign of dehydration in children. In the scenario provided, the child is experiencing increased stool frequency, liquid consistency, fever, and vomiting, indicating fluid loss and potential dehydration. Occult blood in the stool may suggest gastrointestinal bleeding but is not a direct indicator of dehydration. Abdominal distention can be seen in various conditions and is not specific to dehydration. Hyperactive bowel sounds are more commonly associated with increased bowel motility, not necessarily dehydration.
4. A primigravida at term comes to the prenatal clinic and tells the nurse that she is having contractions every 5 min. The nurse monitors the client for one hour, using an external fetal monitor, and determines that the client’s contractions are 7 to 15 minutes apart, lasting 20 to 30 seconds, with mild intensity by palpation. What action should the nurse take?
- A. Tell the client to go directly to the hospital for admission to labor and delivery for active labor
- B. Send the client home and instruct her to call the clinic when her contractions occur 5 minutes apart for one hour
- C. Tell the client to check into the hospital within the next hour for evaluation of possible urinary tract infection
- D. Advise the client to rest and hydrate, then return if contractions become more regular
Correct answer: B
Rationale: The client should be instructed to call when contractions are 5 minutes apart for an hour to ensure she is in active labor before going to the hospital.
5. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled Amoxicillin (Amoxil) suspension 200 mg/5 ml. How many ml should the nurse administer every 8 hours?
- A. 10 ml
- B. 12.5 ml
- C. 15 ml
- D. 17.5 ml
Correct answer: B
Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
