1. During an assessment, an infant is suspected to have intussusception. Which of the following findings should the nurse expect?
- A. Currant jelly stools
- B. Projectile vomiting
- C. Scaphoid abdomen
- D. Frequent stools
Correct answer: A
Rationale: Intussusception is a condition where one segment of the intestine telescopes into another, causing obstruction. The classic presentation includes currant jelly stools, which are a mixture of blood and mucus due to the sloughing of the intestinal mucosa. This finding is a result of the compromised blood supply to the affected area and is a key characteristic associated with intussusception.
2. During an assessment, which manifestation should a healthcare provider expect in an infant with pyloric stenosis?
- A. Bile-stained vomitus
- B. Distended abdomen
- C. Olive-shaped mass in the upper abdomen
- D. Painless, swollen joints
Correct answer: C
Rationale: Pyloric stenosis in infants typically presents with an olive-shaped mass in the upper abdomen due to hypertrophy of the pyloric muscle. This mass can often be palpated during an assessment and is a key characteristic of this condition. Bile-stained vomitus may be seen in conditions such as intestinal obstruction; a distended abdomen can be a nonspecific sign of various conditions, and painless, swollen joints are not typically associated with pyloric stenosis.
3. Which model of practice emphasizes the child's subjective experience of their abilities?
- A. Occupational Adaptation
- B. Model of Human Occupation
- C. Person-Environment-Occupation-Performance Model
- D. Canadian Model of Occupational Performance and Engagement
Correct answer: B
Rationale: The Model of Human Occupation (MOHO) emphasizes the child's subjective experience of their abilities, focusing on their motivation, roles, habits, and routines. It considers how these factors influence their occupational performance. MOHO helps occupational therapists understand how a child's perceptions of their abilities impact their engagement in meaningful activities and occupations.
4. While auscultating the lungs of an adolescent with asthma, what should the nurse identify the sound as?
- A. Biots respiration
- B. Chaney-Stokes respiration
- C. Tachypnea
- D. Bradypnea
Correct answer: C
Rationale: The nurse should identify the sound heard during auscultation as tachypnea, which is characterized by a rapid, regular breathing pattern. In the case of an adolescent with asthma, tachypnea can be indicative of increased work of breathing due to airway constriction and inflammation. Biots respiration (choice A) is characterized by an irregular pattern of breathing with periods of apnea. Chaney-Stokes respiration (choice B) is a pattern of breathing characterized by alternating periods of deep, rapid breathing followed by periods of apnea. Bradypnea (choice D) refers to an abnormally slow breathing rate, which is not typically associated with asthma exacerbation.
5. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?
- A. Angiotensin I
- B. Angiotensin II
- C. Angiotensin III
- D. Renin
Correct answer: B
Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.
