Nurse Angie added that oral contraceptives also contains progesterone. Which of the following is the action of progesterone in contraception? It inhibits _______.

Correct Answer: C

Rationale: Progesterone in oral contraceptives works primarily by inhibiting ovulation. It suppresses the secretion of luteinizing hormone (LH) from the pituitary gland, which is essential for triggering the release of an egg (ovulation) from the ovary. By blocking ovulation, progesterone helps prevent pregnancy by making it less likely for a mature egg to be available for fertilization. This mechanism of action is a key factor in the effectiveness of progesterone-containing contraceptives in preventing pregnancy.

Correct Answer: C

Rationale: Republic Act 9173, also known as the Philippine Nursing Act of 2002, mandates the compulsory immunization of children below 8 years. This law ensures that young children receive necessary vaccines to protect them from preventable diseases and promote public health. RA 9173 is a significant legislation that highlights the importance of immunization in safeguarding the well-being of children in the Philippines.

Correct Answer: A

Rationale: Administering a stool softener as ordered is the most appropriate nursing intervention for a postpartum client experiencing severe perineal pain and difficulty passing stools following a vaginal delivery. Stool softeners help to soften the stool, making it easier for the client to pass without straining, which can exacerbate perineal pain. It is important to follow the healthcare provider's orders when administering medications to ensure proper dosing and effectiveness. Encouraging the client to refrain from defecation may lead to constipation and worsen the situation. Applying ice packs to the perineum can provide temporary pain relief, but addressing the underlying issue of constipation with a stool softener is more effective in the long term. Providing education on proper perineal hygiene is important for overall postpartum care, but addressing the immediate issue of constipation with a stool softener takes precedence in this scenario.

Correct Answer: B

Rationale: The extraneous variable in a study is a variable that is not the main focus of the study but could potentially impact the results. In this case, the length of stay is an extraneous variable because it is not directly related to the research question or objective of the study. The study is likely focused on factors such as patient age, complications, or date of admission, making the length of stay an irrelevant variable in this context.

Correct Answer: C

Rationale: Placing the patient on an alternating pressure mattress demonstrates evidence-based practice in pressure injury prevention. Alternating pressure mattresses are designed to change pressure points by alternating pressure across different parts of the body, reducing the risk of pressure injuries. Regularly turning and repositioning the patient (Choice B) is also important in preventing pressure injuries, but an alternating pressure mattress provides additional support and prevention measures. Applying moisturizing lotion (Choice A) and massaging bony prominences (Choice D) may be beneficial for skin care, but they are not proven strategies for pressure injury prevention.

Correct Answer: A

Rationale: To help the students better understand the anatomy of the breast, it is crucial to provide visual aids that display both external and internal views of the breast. By sharing various pictures of the breast, students can visually learn about the structure, shape, location of different components, such as lobes, ducts, glands, and lymph nodes. Visual aids enhance the learning experience by providing a clear representation of the complex anatomical features of the breast, aiding in retention and comprehension. This approach can effectively supplement theoretical knowledge with practical visual references, facilitating a comprehensive understanding of breast anatomy.

Correct Answer: A

Rationale: Magnetic Resonance Imaging (MRI) is a specialized medical imaging technique that uses magnetic fields and radio waves to create detailed images of the organs and tissues within the body. In the context of the scenario provided, an MRI is ordered by the attending physician to validate the medical impression.

Correct Answer: C

Rationale: Severe nausea and vomiting with a large volume of vomitus can indicate a serious underlying issue such as gastrointestinal obstruction or other medical emergencies. In this situation, it is crucial for the nurse to notify the physician immediately so that further assessment and appropriate management can be initiated promptly. Delay in seeking medical help can lead to complications and worsen the patient's condition. It is important to act quickly and involve the physician in situations where the patient's health may be at risk.

Correct Answer: C

Rationale: When discharging a suicidal patient who has been taking tricyclic antidepressant drugs, it is crucial for the nurse to evaluate the risk for suicide by overdose of the medication. Tricyclic antidepressants have a narrow therapeutic index, meaning that the difference between a therapeutic dose and a toxic dose can be quite small. This makes them particularly dangerous in cases of overdose, as they can lead to severe toxic effects, including cardiac arrhythmias, seizures, and death.
