A nurse is reinforcing teaching with a client who is using a diaphragm to prevent pregnancy. Which of the following statements should the nurse include in the teaching?

Rationale:

A. Milk: Milk does not interfere with fecal occult blood testing and does not contain substances that cause false-positive results. It can be safely consumed prior to the test without affecting the accuracy of the results.

B. Whole wheat bread: Whole wheat bread is high in fiber, which is actually beneficial when preparing for a fecal occult blood test. It helps promote regular bowel movements but does not lead to false-positive results.

C. Red meat: Red meat contains heme, a form of animal blood, which can cause false-positive results on guaiac-based fecal occult blood tests. Avoiding red meat for at least 3 days prior to the test helps reduce the risk of inaccurate results.

D. Almonds: Almonds and other nuts do not contain components that interfere with fecal occult blood testing. They are not known to cause false-positive or false-negative results and are safe to consume before the test.

Rationale:

• Naloxone: The client received fentanyl and is now showing signs of opioid-induced respiratory depression. Respiratory rate has decreased to 10/min and oxygen saturation to 87%. Naloxone will reverse the opioid’s effects and restore adequate respiratory effort.

• An additional dose of propofol: The client’s level of sedation is already too deep, as shown by low respiratory rate and blood pressure. Additional propofol would worsen central nervous system depression. It may cause complete apnea or cardiac compromise in this situation.

• Oxygen 10 L/min via face mask: The current oxygen flow via nasal cannula is insufficient given the client's low oxygen saturation. A face mask delivers higher oxygen concentration and flow. This is critical to correct hypoxia until the cause is reversed.

• Acetaminophen: There is no fever or current complaint of pain requiring antipyretics or analgesics. Administering acetaminophen now would not address the acute respiratory issue. It would delay more urgent and appropriate interventions.

• An additional dose of fentanyl: Administering more opioid would increase the risk of further respiratory depression. The client is already showing hypoventilation and declining oxygenation. More fentanyl would worsen sedation and endanger airway and breathing.

• Propranolol: The client is already hypotensive with a BP of 80/51 mm Hg and a heart rate of 68/min. Giving a beta blocker could severely depress cardiac output. This would increase the risk of organ hypoperfusion and cardiac arrest.
