HESI Medical Surgical Assignment Exam
1. A nurse cares for clients with urinary incontinence. Which types of incontinence are correctly paired with their clinical manifestations? (Select all that apply.)
- A. Stress incontinence – Urine loss with physical exertion
- B. Urge incontinence – Large amount of urine with each occurrence
- C. Overflow incontinence – Constant dribbling of urine
- D. All of the above
Correct answer: D
Rationale: The correct answer is D, as all the choices are correctly paired with their clinical manifestations. Stress incontinence is characterized by urine loss with physical exertion, coughing, sneezing, or exercising. Urge incontinence presents with a sudden and strong urge to void, often accompanied by a large amount of urine released during each occurrence. Overflow incontinence occurs when the bladder is distended, leading to a constant dribbling of urine. Functional incontinence, not mentioned in the options, is the leakage of urine due to factors unrelated to a lower urinary tract disorder. Reflex incontinence, also not mentioned, is a condition resulting from abnormal detrusor contractions.
2. What are the nitrogenous bases of DNA?
- A. Adenine, cytosine, guanine, and thymine
- B. Adenine, guanine, and uracil
- C. Adenine, guanine, and thymine
- D. Adenine, cytosine, guanine, and uracil
Correct answer: A
Rationale: The correct answer is A: Adenine, cytosine, guanine, and thymine. These are the four nitrogenous bases found in DNA. Adenine pairs with thymine, and cytosine pairs with guanine, forming the complementary base pairs in the double helix structure of DNA. Choice B is incorrect because uracil is a nitrogenous base found in RNA, not DNA. Choice C is incorrect as it is missing cytosine, one of the four bases in DNA. Choice D is incorrect because uracil is not a nitrogenous base in DNA, and it also lacks thymine, which is essential for DNA structure.
3. The nurse is caring for a 24-month-old toddler who has sensory sensitivity, difficulty engaging in social interactions, and has not yet spoken two-word phrases. Which assessment should the nurse administer?
- A. Peabody Picture Vocabulary Test
- B. The Modified Checklist for Autism in Toddlers (M-CHAT)
- C. Wechsler Preschool and Primary Scale of Intelligence
- D. Denver Developmental Screening Test
Correct answer: B
Rationale: The Modified Checklist for Autism in Toddlers (M-CHAT) is specifically designed to screen for autism spectrum disorders in young children. It is appropriate for this child, given the signs of social and communication delays. The Peabody Picture Vocabulary Test (Choice A) assesses receptive vocabulary and may not capture the social and communication aspects seen in autism. The Wechsler Preschool and Primary Scale of Intelligence (Choice C) measures cognitive ability and may not address the social and communication delays. The Denver Developmental Screening Test (Choice D) is a broad developmental assessment tool, but the M-CHAT is more specific to screening for autism in this case.
4. 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.
5. During a group session on anger management, a male adolescent client is fidgety, interrupts peers, and talks about his pets at home. What action should the nurse take?
- A. Allow the client to leave and return in 10 minutes.
- B. Explore the client’s feelings about his pets and home life.
- C. Encourage his peers to help involve him in the activity.
- D. Redirect him by encouraging him to read from the handout.
Correct answer: D
Rationale: The best nursing action in this scenario is to redirect the client by encouraging him to read from the handout. This approach helps refocus the client's attention on the topic being discussed, which is anger management. Choice A is not appropriate as it may disrupt the group session and does not address the client's behavior. Choice B, while important in understanding the client's background, does not address the immediate disruptive behavior. Choice C involves others to manage the client's behavior instead of direct intervention by the nurse, which may not be effective in this situation.
