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: B

Rationale: The nurse's priority when a patient appears confused and disoriented during a consultation is to provide clear and simple explanations and assess for any underlying causes of confusion. It is essential to ensure that the patient understands the information being provided and to address any potential reasons for the confusion, such as medication side effects, medical conditions, or cognitive impairment. Ignoring the patient's confusion or assuming they cannot understand can lead to misunderstandings, errors in care, and ultimately jeopardize the patient's well-being. It is crucial to approach the situation with empathy, patience, and a focus on ensuring effective communication and understanding between the nurse and the patient.

Correct Answer: C

Rationale: The patient is likely infected with Cryptosporidium parvum based on the symptoms of watery diarrhea, abdominal cramps, and nausea after consuming contaminated water. Cryptosporidium is a protozoan parasite that can be transmitted through contaminated water sources, such as streams. Laboratory tests revealing oocysts in the stool sample further support the diagnosis of Cryptosporidium infection, as these oocysts are characteristic of this parasite. Giardia lamblia is another common protozoan parasite that can cause similar symptoms but is usually associated with more foul-smelling, greasy diarrhea. Entamoeba histolytica causes amoebic dysentery, which presents with bloody diarrhea and abdominal pain. Cyclospora cayetanensis also causes watery diarrhea, but it is usually associated with foodborne outbreaks rather than waterborne transmission.

Correct Answer: A

Rationale: Tricyclic antidepressants (TCAs) are known to have anticholinergic effects, which can lead to various cardiovascular side effects, including orthostatic hypotension, tachycardia, and potential hypertension. While hypotension is a possible adverse effect, hypertension is more commonly associated with TCAs. Therefore, it is essential for the nurse to monitor the patient for signs of hypertension, such as elevated blood pressure readings, to prevent any adverse outcomes and ensure the patient's safety while on this medication.

Correct Answer: B

Rationale: Cell-mediated immunity is a type of immune response that involves the activation of cytotoxic T cells and other immune cells to directly target and destroy infected or abnormal cells. It does not involve the production of antibodies, which are the primary component of humoral immunity. Antibodies are produced by B cells and are responsible for targeting extracellular pathogens such as bacteria and viruses. In contrast, cell-mediated immunity is more focused on targeting intracellular pathogens, cancerous cells, and other cells that have been compromised. So, production of antibodies is not usually associated with cell-mediated immunity.

Correct Answer: A

Rationale: At the concrete operational stage according to Piaget's theory, children typically demonstrate logical thinking abilities and are able to understand and work with concrete objects and events. They can also grasp concepts such as conservation and classification. These children are able to think logically about concrete events but may still struggle with abstract and hypothetical situations. Therefore, Belle, functioning at the concrete operational stage, would exhibit behaviors such as thinking logically and being able to see possibilities, as described in option A.
