According to Erikson's theory, what behavioral pattern should be displayed by a child who has not developed a sense of competence?

Correct Answer: D

Rationale: Erikson's theory of psychosocial development outlines that the failure to establish a sense of competence during the industry vs. inferiority stage results in feelings of inferiority. This stage occurs during middle childhood where children strive to master skills and tasks. If they are unable to meet challenges successfully, they may start feeling inferior to their peers and may lack confidence in their abilities.

Correct Answer: D

Rationale: A significant drop in heart rate and blood pressure should be reported immediately as it may indicate worsening of the congenital heart defect. A decrease in blood pressure to 70/40 is a critical finding that suggests potential cardiovascular compromise and requires urgent attention to prevent further deterioration.

Correct Answer: A

Rationale: In a 6-year-old child with asthma experiencing difficulty breathing and using accessory muscles to breathe with a peak flow reading in the red zone, the priority intervention is to administer a nebulized bronchodilator first. Nebulized bronchodilators help open the airways quickly, providing immediate relief and improving breathing. This intervention aims to address the acute respiratory distress the child is experiencing before considering other assessments or interventions such as obtaining arterial blood gases, starting oxygen therapy, or contacting the healthcare provider.

Correct Answer: A

Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons.

Correct Answer: B

Rationale: In pediatric patients, digoxin administration is guided by the heart rate. If the child's heart rate is below the established threshold, which is typically 90-100 beats per minute in a 4-year-old, the medication should be withheld, and the healthcare provider should be notified for further evaluation and instructions.

Correct Answer: B

Rationale: When a child with Graves' disease is prescribed propranolol (Inderal), the nurse should monitor for a decreased heart rate as a therapeutic response. Propranolol is a beta-blocker that acts to slow down the heart rate, which is beneficial in managing the symptoms of Graves' disease, such as tachycardia and other cardiovascular manifestations.

Correct Answer: A

Rationale: Completing the full course of antibiotics is crucial in the management of acute rheumatic fever as it helps prevent recurrence and complications. Antibiotics are essential in eradicating the underlying infection that triggers the autoimmune response leading to rheumatic fever. Reinforcing the importance of completing the prescribed antibiotic regimen is vital to ensure the child's recovery and prevent further health issues.

Correct Answer: B

Rationale: The nurse's priority action should be to inspect the child's ears for drainage. This immediate assessment can provide valuable information about the presence of infection or fluid accumulation, which can directly impact the child's hearing. By identifying any signs of drainage, the nurse can promptly address any current issues affecting the child's ear health and hearing abilities.

Correct Answer: A

Rationale: By 6 months of age, infants typically achieve the milestone of rolling over completely. This ability demonstrates increasing strength and coordination. Creeping on all fours, pulling self to a standing position, and assuming a sitting position independently are skills that are usually developed at later stages of infancy.
