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: Maintaining patient confidentiality is a foundational principle in healthcare ethics. Nurses are obligated to keep all information about patients confidential, which means not disclosing any patient-related information to unauthorized individuals. This includes refraining from discussing patient cases with others who are not directly involved in the care of the patient. Sharing patient information without consent can be a breach of trust and privacy, which can have legal and ethical implications. Therefore, in order to uphold the principle of confidentiality, nurses must keep all matters about the patient as a secret.

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: A

Rationale: ** In a patient with ARDS, the priority intervention to manage respiratory failure is to initiate lung-protective mechanical ventilation with low tidal volume. ARDS is characterized by widespread inflammation and injury to the alveoli, leading to impaired gas exchange and severe hypoxemia. Lung-protective ventilation strategies aim to minimize ventilator-induced lung injury by using lower tidal volumes (around 6 mL/kg of predicted body weight) to reduce barotrauma and volutrauma.

Correct Answer: C

Rationale: The description provided is classical for fungal keratitis. Fungal keratitis typically presents with a yellowish-white spot on the cornea, often surrounded by a ring of inflammation. Branching, filamentous opacities extending from the corneal lesion are commonly seen on slit-lamp examination in cases of fungal keratitis. This condition is often associated with risk factors such as trauma with organic material or contact lens wear. Prompt diagnosis and treatment with antifungal agents are crucial in managing fungal keratitis to prevent potential complications.

Correct Answer: A

Rationale: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. It is characterized by the presence of multiple fluid-filled sacs (cysts) within the ovaries, which can be visualized on ultrasound. Women with PCOS often experience menstrual irregularities such as irregular periods or no periods, as well as symptoms of hyperandrogenism like hirsutism (excessive hair growth) and acne. Other common features of PCOS include insulin resistance and obesity. It is important to note that not all women with PCOS will have ovarian cysts, but the presence of multiple cysts is a common finding in this condition.

Correct Answer: A

Rationale: The first step in the management of a chemical splash to the eyes is to irrigate the eyes with clean water. Flushing the affected eye with water helps to remove the chemical and minimize any potential injury. It is important to continue irrigation for at least 15-20 minutes to ensure thorough removal of the chemical. This prompt action can help prevent further damage to the eye and surrounding tissue. It is crucial to remember not to delay irrigation to seek medical advice first, as immediate irrigation is vital in such situations. After irrigating the eyes, further assessment and treatment can be carried out based on the severity of the injury.

Correct Answer: C

Rationale: In this situation, the most appropriate response for the palliative nurse is to validate the patient's feelings of guilt and offer support to address their concerns. It is important to acknowledge the patient's emotions and help them navigate through their guilt in a compassionate and understanding manner. By validating their feelings, the nurse can create a safe space for the patient to express their concerns and work towards finding solutions to alleviate their guilt. This approach fosters trust and a therapeutic relationship between the patient and the nurse, ultimately promoting emotional well-being and facilitating open communication.
