A nurse is preparing to administer digoxin to a 6-month-old infant. Prior to administering the dose, the nurse measures the apical heart rate. The nurse should withhold the dose if the infant's apical heart rate is less than what rate?
The Correct Answer is ["90"]
The nurse should withhold the dose if the infant's apical heart rate is less than 90 beats per minute.
Digoxin is a medication that can slow the heart rate. If an infant's heart rate is already too slow, administering digoxin can increase the risk of bradycardia, a serious heart rhythm disturbance.
It's important to monitor the apical heart rate for a full minute before administering digoxin to an infant and to withhold the dose if the heart rate is below the specified threshold.

Explanation
A.Move furniture away from the child.
Explanation: Creating a safe environment is important during a seizure. Moving furniture away from the child helps prevent injury.
B.Place the child in a prone position.
Explanation: Placing the child in a prone position (face down) is not recommended. The child should be placed on their side to allow for drainage of oral secretions and to prevent aspiration.
C. Restrain the child.
Explanation: Restraint is generally not recommended during a seizure, as it may cause injury to the child or the person providing care. Allow the seizure to run its course, and focus on keeping the environment safe.
D.Time the seizure.
Explanation: Timing the duration of the seizure is important for medical evaluation and management. Note the start and end times of the seizure.
E. Insert a padded tongue blade in the child's mouth.
Explanation: Inserting any object, including a padded tongue blade, into the child's mouth during a seizure is not recommended. This can lead to oral and dental injuries. Maintaining a clear airway and protecting the child from injury are priorities.
F. Stay with the child.
Explanation: Staying with the child provides support and ensures the child's safety during the seizure. It also allows the caregiver to observe and provide information to healthcare professionals.
Correct Answer is A
Explanation
A. Heat intolerance
Explanation:
Graves' disease is an autoimmune disorder that results in hyperthyroidism, meaning there is an overproduction of thyroid hormones. Common symptoms of Graves' disease include heat intolerance, increased sweating, weight loss, palpitations, and anxiety. The hyperactivity of the thyroid gland leads to an increased metabolic rate, causing heat intolerance.
B. Bradycardia
Explanation: Bradycardia (slow heart rate) is not typically associated with Graves' disease. Hyperthyroidism usually leads to an increased heart rate (tachycardia) due to the stimulatory effects of thyroid hormones on the cardiovascular system.
C. Lethargy
Explanation: Lethargy (excessive tiredness or lack of energy) is more commonly associated with hypothyroidism, where there is an insufficient production of thyroid hormones. In Graves' disease, the excess thyroid hormones often lead to symptoms of hyperactivity, not lethargy.
D. Weight gain
Explanation: Weight gain is not a typical finding in Graves' disease. Hyperthyroidism often leads to unintentional weight loss due to increased metabolism and energy expenditure. Weight gain is more commonly associated with hypothyroidism.
