A nurse is preparing to administer vaccines to a 4-month-old infant. Which of the following vaccines should the nurse plan to administer?
Influenza
Rotavirus
Measles, mumps, rubella (MMR)
Varicella (VAR)
The Correct Answer is B
A. Influenza:
The influenza vaccine is typically administered annually starting at 6 months of age. It helps protect against seasonal influenza viruses and is usually recommended during the fall or winter months.
B. Rotavirus:
The rotavirus vaccine is routinely administered to infants starting at 2 months of age, with additional doses given at 4 and 6 months of age. It helps prevent rotavirus infection, which can cause severe diarrhea and vomiting in infants and young children.
C. Measles, mumps, rubella (MMR):
The MMR vaccine is typically administered around 12-15 months of age, with a second dose given at 4-6 years of age. It helps protect against measles, mumps, and rubella, which are contagious viral infections that can cause serious complications.
D. Varicella (VAR):
The varicella vaccine, also known as the chickenpox vaccine, is usually administered around 12-15 months of age, with a second dose given at 4-6 years of age. It helps prevent chickenpox, a highly contagious viral infection characterized by a rash and fever.

Correct Answer is B
Explanation
A. Maintain a saline-lock:
While maintaining a saline lock is important for ensuring vascular access in case of emergency, it is not the priority action in caring for a child with acute glomerulonephritis. Monitoring fluid balance and electrolyte levels may be necessary, but the immediate priority is to educate the parents about potential complications.
B. Check the child's weight daily:
Monitoring daily weight is crucial in acute glomerulonephritis, as it helps assess fluid balance and detect early signs of fluid retention or worsening kidney function, which are key concerns in this condition. This makes it a priority action.
C. Place the child on a no-salt-added diet:
Dietary modifications, including reducing salt intake, may be recommended for managing acute glomerulonephritis. However, it is not the priority action at this stage.
D. Educate the parents about potential complications:
Parental education is important for long-term management and understanding of the condition, but it is not the most immediate priority in the acute phase of the illness.
Correct Answer is ["A","D","E"]
Explanation
A. Wheezing: Wheezing is a common symptom associated with asthma, which can be exacerbated by gastroesophageal reflux (GER) in infants. GER occurs when stomach contents flow back into the esophagus, leading to irritation and inflammation of the airways. This inflammation can cause wheezing sounds during breathing, especially if the refluxed material reaches the lower respiratory tract.
B. Rigid abdomen: While gastroesophageal reflux (GER) primarily affects the upper gastrointestinal tract, it typically does not cause a rigid abdomen. A rigid abdomen may indicate other underlying gastrointestinal issues such as bowel obstruction, intussusception, or peritonitis. These conditions are not typically associated with GER in infants.
C. Pallor: Pallor, or paleness of the skin, is not a common symptom of gastroesophageal reflux (GER) in infants. GER primarily affects the upper gastrointestinal tract and is characterized by symptoms such as spitting up, regurgitation, and irritability. Pallor may be indicative of other health issues such as anemia or circulatory problems but is not directly related to GER.
D. Weight loss: Weight loss can occur in infants with gastroesophageal reflux (GER) if frequent vomiting leads to inadequate intake of nutrients. However, it is not a direct symptom of GER itself. Infants with GER may experience feeding difficulties, irritability, and discomfort associated with feeding, which can contribute to poor weight gain over time if not managed effectively.
E. Vomiting: Vomiting is a common symptom of gastroesophageal reflux (GER) in infants. It occurs when stomach contents flow back up into the esophagus and sometimes out of the mouth. Infants with GER may spit up or vomit frequently after feeding or during burping, which can lead to discomfort and irritability. Vomiting may also contribute to poor weight gain and nutritional deficiencies if not managed effectively.
