A nurse is teaching a class about pulmonary circulation. The nurse should include that blood flows from the heart to the lungs from the right ventricle starting from which of the following locations?

A) "Take the medication with a full glass of water":
This is the correct answer. Docusate is a stool softener used to treat constipation by promoting the incorporation of water into the stool, making it softer and easier to pass. Taking docusate with a full glass of water helps facilitate its action by ensuring hydration and aiding in the softening of stool.

B) "Take this medication on an empty stomach":
Taking docusate on an empty stomach is not necessary. It can be taken with or without food. The primary consideration is to take it with an adequate amount of water to facilitate its stool-softening effect.

C) "Do not take this medication before bedtime":
There is no specific contraindication to taking docusate before bedtime. The timing of administration can vary based on individual preferences and bowel habits. Some individuals may prefer to take it before bedtime to promote a bowel movement in the morning, while others may take it at different times of the day.

D) "Expect abdominal pain with this medication":
Abdominal pain is an uncommon side effect of docusate. While it may occur in some individuals, it is not a common or expected reaction to the medication. Most people tolerate docusate well, but gastrointestinal side effects such as mild abdominal cramping, nausea, or diarrhea may occur in some cases.

A) Respiratory rate 18/min:
A respiratory rate of 18/min is within the normal range for adults and is not a contraindication for administering atenolol. This finding does not warrant withholding the medication.

B) Oxygen saturation 95%:
An oxygen saturation of 95% is within the normal range and does not indicate any acute respiratory compromise. It is not a contraindication for administering atenolol.

C) Heart rate 46/min:
A heart rate of 46/min is below the normal range (typically 60-100 beats per minute for adults). Atenolol is a beta-blocker that primarily acts to reduce heart rate and blood pressure. Administering atenolol to a client with bradycardia (heart rate less than 60/min) can further decrease heart rate and may lead to symptomatic bradycardia or heart block. Therefore, the nurse should withhold atenolol in this case and notify the healthcare provider.

D) Blood pressure 160/94 mm Hg:
A blood pressure of 160/94 mm Hg indicates hypertension (elevated blood pressure). While atenolol is often prescribed for the management of hypertension, this blood pressure reading alone does not warrant withholding the medication. However, the client's bradycardia (heart rate 46/min)’is a more immediate concern that requires action."
