The normal range of hemoglobin in the blood of an adult:
- A. 7-11 mg
- B. 14-20 mg
- C. 12-18 mg
- D. 20-26 mg
Correct Answer: C
Rationale: The normal range of hemoglobin in the blood of an adult is typically between 12-18 grams per deciliter (g/dL). Hemoglobin is a protein found in red blood cells that is responsible for carrying oxygen from the lungs to the tissues in the body. Having an adequate level of hemoglobin is essential for proper oxygen delivery throughout the body. Values outside of the normal range may indicate anemia (low hemoglobin levels) or other underlying health conditions. It's important to consult a healthcare provider for interpretation of specific hemoglobin test results.

Which is the central factor responsible for respiratory distress syndrome?
- A. Deficient surfactant production
- B. Overproduction of surfactant
- C. Overdeveloped alveoli
- D. Absence of alveoli
Correct Answer: A
Rationale: Respiratory distress syndrome is primarily caused by deficient surfactant production in premature infants. Surfactant is a substance that coats the alveoli in the lungs and helps to reduce surface tension, preventing the collapse of the alveoli during exhalation. In premature infants, the lungs may not have produced enough surfactant, leading to difficulty in breathing and inadequate oxygen exchange. This results in respiratory distress syndrome, which is characterized by severe breathing problems in newborns. Overproduction of surfactant, overdeveloped alveoli, or absence of alveoli are not central factors in the development of respiratory distress syndrome.
A patient is having difficulty swallowing following a stroke, and a swallowing evaluation is ordered. The ff. nursing interventions might be recommended to help prevent aspiration during eating except:
- A. Provide clear liquids only until the patient can swallow solid foods.
- B. Have the patient swallow twice after each bite
- C. Place food on the unaffected side of the patient's mouth
- D. Check if the patient's mouth for pocketing of food
Correct Answer: A
Rationale: Providing clear liquids only until the patient can swallow solid foods is not recommended as it restricts the patient's diet unnecessarily. In the case of difficulty swallowing after a stroke, it is important to modify the food consistency and provide appropriate techniques to support safe swallowing. Limiting the patient to clear liquids only could lead to inadequate nutrition and hydration. Instead, it is important to modify the diet consistency and use strategies such as altering the food presentation, having the patient swallow twice after each bite, placing food on the unaffected side of the mouth, and checking for pocketing of food to help prevent aspiration.
The nurse is aware that the most common assessment finding in a child with ulcerative colitis is:
- A. Intense abdominal cramps
- B. Profuse diarrhea
- C. Anal fissures
- D. Abdominal distention
Correct Answer: B
Rationale: Profuse diarrhea is the most common assessment finding in a child with ulcerative colitis. Ulcerative colitis is a type of inflammatory bowel disease that primarily affects the colon and rectum. It causes inflammation and ulcers in the lining of the colon, leading to symptoms such as frequent and urgent bowel movements, abdominal pain, and bloody diarrhea. The diarrhea in ulcerative colitis is typically watery and can be very severe, often leading to dehydration and electrolyte imbalances. Intense abdominal cramps, anal fissures, and abdominal distention can also be present in ulcerative colitis, but profuse diarrhea is the hallmark symptom that is commonly seen in affected children.
A parent asks the nurse "at what age do most infants begin to fear strangers?" The nurse should give which response?
- A. 2 months
- B. 4 months
- C. 6 months
- D. 12 months
Correct Answer: C
Rationale: Most infants begin to exhibit fear or stranger anxiety around 6 months of age. This is a normal developmental stage where infants become more aware of their surroundings and become wary of unfamiliar people. Infants may become anxious or cry when approached by strangers, showing that they prefer familiar faces like parents or caregivers. This behavior typically peaks between 6 to 9 months and gradually decreases as the child grows older and gains more social experience.
The physical abuse of children affects children of all ages. Serious injuries, such as head or abdominal trauma, are more likely to be inflicted by
- A. mothers
- B. fathers
- C. old brothers
- D. grand mothers
Correct Answer: B
Rationale: Fathers and male caregivers are statistically more likely to inflict serious physical abuse, including head and abdominal trauma, due to greater physical strength and aggression.
