HESI Medical Surgical Exam
1. What is the most common cause of urinary tract infections (UTIs)?
- A. Escherichia coli infection
- B. Staphylococcus aureus infection
- C. Pseudomonas aeruginosa infection
- D. Klebsiella pneumoniae infection
Correct answer: A
Rationale: Escherichia coli is the most common cause of urinary tract infections (UTIs). It is responsible for the majority of UTIs, especially in women. E. coli is a normal inhabitant of the bowel and can enter the urinary tract through the urethra, leading to infection. Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae are less common causes of UTIs compared to E. coli. Staphylococcus aureus typically causes skin and soft tissue infections, Pseudomonas aeruginosa is more commonly associated with healthcare-associated infections, and Klebsiella pneumoniae is known for causing pneumonia and other respiratory infections.
2. According to Erikson's theory, what behavioral pattern should be displayed by a child who has not developed a sense of competence?
- A. Guilt.
- B. Shame.
- C. Alienation.
- D. Inferiority.
Correct answer: D
Rationale: Erikson's theory of psychosocial development outlines that the failure to establish a sense of competence during the industry vs. inferiority stage results in feelings of inferiority. This stage occurs during middle childhood where children strive to master skills and tasks. If they are unable to meet challenges successfully, they may start feeling inferior to their peers and may lack confidence in their abilities. Choices A, B, and C are incorrect as guilt, shame, and alienation are not the specific behavioral patterns associated with the lack of developing a sense of competence according to Erikson's theory.
3. The RN on the evening shift receives a report that a client is scheduled for electroconvulsive treatment (ECT) in the morning. Which intervention should the RN implement the evening before the scheduled ECT?
- A. Hold all bedtime medications.
- B. Keep the client NPO after midnight.
- C. Implement elopement precautions.
- D. Give the client an enema at bedtime.
Correct answer: B
Rationale: Keeping the client NPO after midnight is the appropriate intervention before ECT to prevent complications during the procedure. Withholding food and fluids reduces the risk of aspiration and helps ensure the safety of the client. Option A (Hold all bedtime medications) is incorrect because medications may need to be given as prescribed unless specified otherwise by the healthcare provider. Option C (Implement elopement precautions) is unrelated to preparing a client for ECT and focuses on preventing a client from leaving the treatment area. Option D (Give the client an enema at bedtime) is unnecessary and not a standard pre-ECT preparation, making it an incorrect choice.
4. When performing a health history on a patient who is to begin receiving a thiazide diuretic to treat heart failure, the nurse will be concerned about a history of which condition?
- A. Asthma
- B. Glaucoma
- C. Gout
- D. Hypertension
Correct answer: C
Rationale: Thiazide diuretics block uric acid secretion, leading to elevated levels that can contribute to gout. Therefore, patients with a history of gout should take thiazide diuretics with caution. Asthma (Choice A), Glaucoma (Choice B), and Hypertension (Choice D) are not directly contraindicated with thiazide diuretics, making choices A, B, and D incorrect.
5. One hour after delivery, the nurse is unable to palpate the uterine fundus of a client and notes a large amount of lochia on the perineal pad. Which intervention should the nurse implement first?
- A. Empty the bladder using an indwelling urinary catheter
- B. Increase the rate of the IV containing oxytocin (Pitocin)
- C. Assess for shock by determining the blood pressure
- D. Perform gentle massage at the level of the umbilicus
Correct answer: D
Rationale: Gentle massage at the level of the umbilicus is the initial intervention to help contract the uterus and reduce bleeding, which is crucial in managing postpartum hemorrhage. Emptying the bladder can help with fundal displacement, but massage should be done first to stimulate uterine contractions. Increasing the IV oxytocin rate is a possible intervention but not the initial priority. Assessing for shock is important, but addressing the uterine atony through massage takes precedence to prevent further hemorrhage.
