After inflating a blood pressure cuff and releasing the valve, the nurse hears silence followed by a Korotkoff sound.
Which action should the nurse take next?

The correct answer is choice d. Activate the lockdown procedure.

Choice A rationale:

Asking the mother if any visitors were expected to arrive is important for gathering information, but it is not the immediate priority when a newborn is missing. The primary concern is to ensure the safety and security of the infant.

Choice B rationale:

Matching ID bands of all infants and mothers on the unit is a crucial step in verifying the identity of the newborn, but it should be done after ensuring that the unit is secure and the baby cannot be taken out of the facility.

Choice C rationale:

Determining if the newborn is in the nursery is also important, but it should be done after securing the unit to prevent any potential abduction.

Choice D rationale:

Activating the lockdown procedure is the first and most critical action. This ensures that all exits are secured, preventing anyone from leaving the unit with the infant. It is a safety measure to protect the newborn and is the immediate priority in such situations.

Choice A rationale:

Supplemental oxygen is given to the patient to prevent hypoxia and tissue damage due to pneumonia. Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. Hypoxia occurs when the body or a region of the body is deprived of adequate oxygen supply at the tissue level. It can cause serious damage to your heart, brain, and other organs. Hence, supplemental oxygen is administered to ensure that the patient’s tissues receive adequate oxygen.

Choice B rationale:

While supplemental oxygen can indirectly help lower blood pressure by improving oxygen supply and reducing strain on the heart, it is not primarily used for this purpose. Enalapril, which the patient is already taking, is an angiotensin-converting enzyme (ACE) inhibitor that is commonly used to lower blood pressure and reduce the workload of the heart.

Choice C rationale:

Supplemental oxygen does increase the oxygen saturation and improve respiratory function. However, this is a more general rationale for providing supplemental oxygen and not specific to this patient’s condition of pneumonia.

Choice D rationale:

Supplemental oxygen does not directly dilate the bronchioles or decrease inflammation in the lungs. Medications such as bronchodilators and corticosteroids are typically used for these purposes. In this case, supplemental oxygen is being used to prevent hypoxia and tissue damage due to pneumonia.
