1. What complication of mumps is crucial for adolescents to prevent?
- A. Sterility
- B. Hypopituitarism
- C. Decreased libido
- D. Decreased androgens
Correct answer: A
Rationale: The correct answer is A, Sterility. Mumps can lead to sterility, particularly in adolescent males, highlighting the significance of vaccination to prevent this serious complication. While hypopituitarism (choice B) can be a potential complication of mumps, it is not as crucial to prevent in adolescents compared to the risk of sterility. Choices C and D, Decreased libido and Decreased androgens, are not direct complications of mumps and are not the primary concerns for adolescents in relation to mumps prevention.
2. A young child has coarctation of the aorta. What does the nurse expect to identify when taking the child’s vital signs?
- A. A weak radial pulse
- B. An irregular heartbeat
- C. A bounding femoral pulse
- D. An elevated radial blood pressure
Correct answer: A
Rationale: In coarctation of the aorta, there is narrowing of the aorta leading to decreased blood flow distal to the constriction. This results in a weak or delayed femoral pulse and a relatively weaker radial pulse compared to the femoral pulse. An irregular heartbeat (choice B) is not a typical finding in coarctation of the aorta. A bounding femoral pulse (choice C) would not be expected due to the decreased blood flow beyond the constriction. An elevated radial blood pressure (choice D) is not a common characteristic of coarctation of the aorta; instead, blood pressure may be higher in the upper extremities compared to the lower extremities due to the constriction.
3. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:
- A. nondisjunction.
- B. X-linked recessive inheritance.
- C. genomic imprinting.
- D. autosomal dominant inheritance.
Correct answer: A
Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.
4. Following delivery of a newborn, the 21-year-old mother is experiencing mild vaginal bleeding. You note that her heart rate has increased from 90 to 120 beats/min and she is diaphoretic. Management should include
- A. oxygen, uterine massage, and transport
- B. oxygen, placement on the left side, and transport
- C. oxygen, treatment for shock, and uterus massage during transport
- D. oxygen, internal vaginal pads, and treatment of shock during transport
Correct answer: C
Rationale: Postpartum hemorrhage can lead to shock due to excessive bleeding. Oxygen should be provided to support oxygenation. Treatment for shock, which includes maintaining vital signs and perfusion, is crucial. Uterine massage helps prevent further bleeding by promoting uterine contraction. This combination of interventions is essential for managing postpartum hemorrhage effectively. Choices A, B, and D lack the comprehensive approach needed for managing postpartum hemorrhage, as they do not address the treatment of shock, which is vital in this scenario.
5. A healthcare professional is reviewing the clinical records of infants and children with cardiac disorders who developed heart failure. What did the professional determine is the last sign of heart failure?
- A. Tachypnea
- B. Tachycardia
- C. Peripheral edema
- D. Periorbital edema
Correct answer: C
Rationale: Peripheral edema is often considered the last sign of heart failure in infants and children. It indicates significant fluid retention and circulatory compromise. Tachypnea (increased respiratory rate) and tachycardia (increased heart rate) are early signs of heart failure due to inadequate cardiac output. Periorbital edema, while a sign of excess fluid, typically occurs earlier in the progression of heart failure compared to peripheral edema.
