Which of the following is NOT an infectious cause of diarrheal diseases?
- A. Allergy
- B. Bacterial
- C. Parasitic
- D. Viral
Correct Answer: A
Rationale: Allergy is the correct answer as it is a non-infectious cause of diarrheal diseases. While bacterial, parasitic, and viral infections can lead to diarrhea by affecting the gastrointestinal tract, allergies are immune system reactions triggered by specific substances and are not caused by infectious agents. Bacterial, parasitic, and viral infections are known to cause infectious diarrhea, making choices B, C, and D incorrect.

Warning signs that indicate dehydration include all EXCEPT:
- A. Poor skin turgor
- B. Increased urine output
- C. Tachycardia
- D. Eager to drink
Correct Answer: B
Rationale: The correct answer is B. Increased urine output is not a warning sign of dehydration; it typically decreases with dehydration. Dehydration often presents with poor skin turgor, tachycardia, and an increased sensation of thirst (eager to drink) as the body tries to compensate for fluid loss. Choices A, C, and D are all correct warning signs of dehydration. Poor skin turgor is a result of decreased skin elasticity due to fluid loss. Tachycardia, an elevated heart rate, can be a compensatory mechanism to maintain cardiac output in dehydration. Feeling eager to drink is a common symptom of dehydration as the body attempts to restore fluid balance.
A new mother asks the nurse when she should begin to breastfeed her newborn. The nurse's best response is:
- A. Within the first half-hour after birth
- B. After the newborn's first bath
- C. When the newborn begins to cry
- D. After administering vitamin K
Correct Answer: A
Rationale: Initiating breastfeeding within the first half-hour after birth is crucial for successful breastfeeding and bonding, as recommended by the World Health Organization. This early initiation helps establish breastfeeding and supports the newborn's health by providing colostrum, the nutrient-rich first milk. Choice B, 'After the newborn's first bath,' is incorrect because initiating breastfeeding should not be delayed after birth. Choice C, 'When the newborn begins to cry,' is incorrect as it does not promote timely initiation of breastfeeding. Choice D, 'After administering vitamin K,' is incorrect because breastfeeding initiation should not be delayed for this procedure.
Are most children with hypertension asymptomatic?
- A. TRUE
- B. FALSE
Correct Answer: A
Rationale: The statement is true. In many cases, children with hypertension do not show any symptoms, making it challenging to diagnose them. Regular blood pressure checks are crucial to detect hypertension early, as it can have serious health implications if left untreated. Choice B is incorrect because most children with hypertension do not exhibit symptoms, hence being asymptomatic. Choices C and D are empty as they do not provide additional options.
One of the signs of CHF is shortness of breath. What is the term for shortness of breath when lying down?
- A. Platypnea
- B. Orthopnea
- C. Apnea
- D. Epistaxis
Correct Answer: B
Rationale: Orthopnea is the specific term used to describe shortness of breath when lying down. This condition is commonly seen in patients with congestive heart failure (CHF) due to the redistribution of fluid in the body when changing positions. Platypnea refers to shortness of breath that worsens when sitting or standing, apnea is the cessation of breathing, and epistaxis is the medical term for a nosebleed. Therefore, the correct answer is B (Orthopnea).
The nurse is using the New Ballard Score to assess the gestational age of a newborn delivered 4 hours ago. The infant's gestational age is 33 weeks based on early ultrasound and last menstrual period. The nurse expects the infant to exhibit which of the following?
- A. Full sole creases, nails extending beyond the fingertips, scarf sign showing the elbow beyond the midline
- B. Testes located in the upper scrotum, rugae covering the scrotum, vernix covering the entire body
- C. Ear cartilage folded over, lanugo present over much of the body, slow recoil time
- D. 1 cm breast bud, peeling skin and veins not visible, rapid recoil of legs and arms to extension
Correct Answer: C
Rationale: The correct answer is C. Ear cartilage folded over, lanugo present over much of the body, and slow recoil time are all characteristics of a preterm infant. A is incorrect because full sole creases, nails extending beyond the fingertips, and scarf sign showing the elbow beyond the midline are features of a term infant. B is incorrect as testes located in the upper scrotum, rugae covering the scrotum, and vernix covering the entire body are also indicative of a term infant. D is incorrect because a 1 cm breast bud, peeling skin and veins not visible, and rapid recoil of legs and arms to extension are characteristics seen in a more mature infant, not a preterm newborn.
