Adult Health Nursing First Chapter Quizlet

Correct Answer: A

Rationale: Ventilator-associated pneumonia (VAP) is a serious complication in patients receiving mechanical ventilation in the ICU. The priority intervention to manage respiratory infection in a patient with VAP is the administration of appropriate antibiotics to target and eliminate the causative pathogens. Broad-spectrum antibiotics are usually initiated empirically to cover a wide range of potential pathogens commonly associated with VAP, such as Pseudomonas aeruginosa, Staphylococcus aureus, and Acinetobacter species. Timely initiation of antibiotic therapy is crucial in improving outcomes and reducing morbidity and mortality associated with VAP. Other interventions like endotracheal suctioning, oral hygiene measures, and early mobilization are also important in preventing complications and promoting recovery, but the primary focus should be on treating the infection with antibiotics.

Correct Answer: B

Rationale: Support in maintaining a sense of control is essential in keeping the patient calm during labor. Giving the patient a sense of control allows them to feel empowered and more in charge of their experience. This can help reduce anxiety and fear, ultimately promoting a more positive and calm labor experience. Providing emotional support by assisting the patient in maintaining control can greatly benefit their overall emotional well-being during this stressful time.

Correct Answer: C

Rationale: The described presentation of a yellowish-white spot on the cornea with a ring of inflammation, along with branching, filamentous opacities extending from the corneal lesion, is characteristic of fungal keratitis. Fungal keratitis typically presents with these specific features on clinical examination.

Correct Answer: D

Rationale: In a 55-year-old postmenopausal woman presenting with vaginal bleeding and a healthy cervix on examination, the most likely cause would be a cervical polyp. Cervical polyps are benign growths that can occur on the cervix and are often asymptomatic but can occasionally cause postmenopausal bleeding. Their appearance on examination would typically be a non-malignant finding with no cervical motion tenderness. Cervical cancer, endometrial cancer, and vaginal cancer would typically present with different examination findings and risk factors.

Correct Answer: A

Rationale: Estrogen exerts negative feedback on the hypothalamus by inhibiting the release of GnRH (Gonadotropin-Releasing Hormone). GnRH plays a crucial role in the regulation of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) production from the pituitary gland. By inhibiting the release of GnRH, estrogen ultimately leads to a decrease in FSH and LH levels. This process helps to suppress the maturation of the egg and ovulation, providing contraceptive effects.
