HESI Focus on Maternity Exam
1. Twenty-year-old Jack is extremely tall and has very thick facial hair. Most of his male secondary sex characteristics are also more pronounced than men of his age. In this scenario, Jack is most likely:
- A. an XYY male.
- B. diagnosed with Klinefelter syndrome.
- C. an XXY male.
- D. diagnosed with Down syndrome.
Correct answer: A
Rationale: The correct answer is A: an XYY male. Individuals with XYY syndrome often exhibit increased height and more pronounced secondary male characteristics, such as thick facial hair. Choice B, Klinefelter syndrome (XXY), typically presents with less prominent male secondary sex characteristics due to the presence of an extra X chromosome. Choice C, XXY male, refers to Klinefelter syndrome, which does not align with the description of Jack having more pronounced male secondary sex characteristics. Choice D, Down syndrome, is caused by a trisomy of chromosome 21 and is not associated with the physical characteristics described in the scenario.
2. What is a common sign of developmental dysplasia of the hip (DDH) in infants?
- A. Dislocated patella
- B. Limited abduction of the hip
- C. Swelling of the knee
- D. Hyperextension of the leg
Correct answer: B
Rationale: Limited abduction of the hip is a common sign of developmental dysplasia of the hip in infants. It indicates possible hip dislocation or instability, making it a key clinical manifestation to assess for DDH. Dislocated patella (Choice A) is not typically associated with DDH. Swelling of the knee (Choice C) and hyperextension of the leg (Choice D) are not specific signs linked to DDH in infants, further supporting why they are incorrect choices.
3. A client is expressing anger about his diagnosis of colorectal cancer. Which of the following actions should the nurse take?
- A. Reassure the client that this is an expected response to grief.
- B. Ignore the client’s anger and continue with the plan of care.
- C. Tell the client that anger is not going to help his situation.
- D. Encourage the client to express his anger.
Correct answer: A
Rationale: When a client is expressing anger about a diagnosis, it is essential for the nurse to validate the client's feelings. Choice A is correct because reassuring the client that anger is an expected response to grief acknowledges the client's emotions and encourages expression, fostering a therapeutic relationship. This validation helps the client feel understood and supported during a challenging time. Choice B is incorrect as ignoring the client's anger can lead to feelings of neglect and hinder effective communication, which is crucial for providing holistic care. Choice C is inappropriate because telling the client that anger is not helpful dismisses the client's emotions and can further escalate the situation, potentially damaging the nurse-client relationship. Choice D is not the best option as it does not involve acknowledging the client's feelings or providing support and validation, which are vital in promoting emotional well-being and trust between the client and the nurse.
4. A nurse on a medical-surgical unit is dividing care for four clients. The nurse should identify which of the following situations as an ethical dilemma?
- A. A client who has a new colostomy refuses to take instructions from the ostomy therapist because she 'doesn't like him.'
- B. A surgeon who removed the wrong kidney during a surgical procedure refuses to take responsibility for her actions.
- C. The family of a client who has a terminal illness asks the provider not to tell the client the diagnosis.
- D. A client who has Crohn's disease reports that his prescription drug plan will not pay for his medications.
Correct answer: C
Rationale: The correct answer is C because an ethical dilemma involves conflicting moral principles. In this scenario, the family's request not to disclose the terminal diagnosis to the client raises the moral question of truth-telling and patient autonomy. Choice A does not present an ethical dilemma but rather a challenge in client compliance. Choice B involves professional responsibility and accountability, not an ethical dilemma. Choice D relates to financial concerns and insurance coverage, which do not constitute an ethical dilemma but rather a financial issue.
5. A healthcare professional is preparing to administer gentamicin 2 mg/kg via IV bolus to a client who weighs 220 lb. How many mg should the healthcare professional administer?
- A. 200 mg
- B. 100 mg
- C. 160 mg
- D. 180 mg
Correct answer: C
Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg × 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.
