A nurse is caring client who has peptic ulcer disease and is scheduled to undergo an esophagogastroduodenoscopy. Which of the following actions should the nurse take prior to the procedure?

A) "The headaches should decrease as you get used to the medication.": This statement is correct. A common side effect of isosorbide dinitrate is headaches, as the medication works by dilating blood vessels, which can cause a drop in blood pressure. These headaches typically occur when the medication starts, but they often decrease over time as the body adjusts to the drug. The nurse should reassure the client that this side effect is generally temporary.

B) "You should take the medication on an empty stomach to prevent a headache.": This statement is incorrect. While taking certain medications on an empty stomach may affect their absorption, isosorbide dinitrate is typically not recommended to be taken on an empty stomach to avoid headaches. In fact, it is more common for people to take it with food if it causes gastrointestinal discomfort, but this is not directly related to preventing headaches.

C) "You can discontinue the medication until the headache goes away.": This statement is incorrect. The client should not discontinue the medication without consulting the healthcare provider. Abruptly stopping isosorbide dinitrate can lead to withdrawal symptoms and potentially worsen the client's condition. The nurse should encourage the client to talk to their provider if the headache becomes unbearable or persistent, but not to stop the medication without guidance.

D) "Swallow the tablet whole to minimize your headaches.": This statement is incorrect. Isosorbide dinitrate in chewable form is designed to be chewed, as this method of administration helps the drug be absorbed more quickly and effectively. Swallowing the tablet whole would not address the issue of headaches and could affect how the medication works.

A) Rolls from back to abdomen: Rolling from back to abdomen is a typical developmental milestone for a 4-month-old infant. By this age, infants usually have increased muscle strength and coordination, allowing them to start rolling over. This movement helps build their core strength, which is important for later developmental milestones like sitting up and crawling.

B) Moves objects to mouth: It is common for a 4-month-old to move objects to their mouth as they begin exploring the world around them. This action is a key part of sensory development and helps infants develop their hand-to-mouth coordination. Additionally, this behavior assists in teething and the development of oral motor skills.

C) Anterior fontanel closed: The anterior fontanel normally closes between 12 to 18 months of age. If it is closed at 4 months, it may suggest abnormal cranial growth, such as craniosynostosis, where the sutures of the skull close too early. This could lead to increased pressure on the brain, which can cause developmental delays or other complications, so the provider should be notified for further assessment.

D) Posterior fontanel closed: The posterior fontanel typically closes by 2 to 3 months of age. If it is closed by 4 months, it is completely normal and indicates proper cranial development. The closing of the posterior fontanel helps ensure the skull's bones are fusing together as expected, and it does not raise any concerns at this stage.
