Correct Answer: A

Rationale: Implied consent is the type of consent that allows healthcare providers to assume appropriate medical treatment in emergency situations where a patient is unable to give consent. In these cases, it can be assumed that a reasonable person would consent to life-saving treatment if they were able to do so. Implied consent is based on the principle of necessity and prioritizes the patient's well-being when time is of the essence. It is crucial in emergency situations to act quickly to provide the necessary medical care to save a patient's life, even if they are unable to provide express consent at that moment.

Correct Answer: D

Rationale: Spiral CT angiography is the most appropriate test for confirming the diagnosis of pulmonary embolism (PE) in a patient with suspected PE. It is a non-invasive imaging modality that can detect filling defects within the pulmonary vasculature indicative of a clot. This diagnostic test has high sensitivity and specificity for diagnosing PE, making it a valuable tool in the management of patients with suspected PE.

Correct Answer: C

Rationale: Antipsychotic medications, especially first-generation antipsychotics, can cause extrapyramidal symptoms (EPS) as an adverse effect. EPS include symptoms such as muscle rigidity, tremors, akathisia (restlessness), and tardive dyskinesia (involuntary movements of the face and body). These symptoms are due to the medications' effects on the dopamine system in the brain. It is crucial for the nurse to monitor the patient closely for EPS because they can be uncomfortable, distressing, and may impact the patient's quality of life and medication adherence. Early recognition and management of EPS are essential to prevent further complications and improve the patient's overall well-being.

Correct Answer: D

Rationale: The aim of pelvic muscle exercises for a patient with urinary incontinence is to strengthen the muscles that control the vagina and urethra. These exercises, known as Kegel exercises, target the pelvic floor muscles that support the pelvic organs and help in controlling urinary function. Strengthening these muscles can help improve bladder control and reduce or eliminate urinary incontinence. Exercises that target the perineal area can also be beneficial in managing urinary incontinence, but the main focus is on strengthening the muscles that control the vagina and urethra.

Correct Answer: B

Rationale: The laboratory test used to monitor the therapeutic effect of warfarin therapy is the International Normalized Ratio (INR). Warfarin is a commonly prescribed anticoagulant medication that works by inhibiting the action of vitamin K-dependent clotting factors. Maintaining the INR within the target range specific to the indication for anticoagulation (e.g., DVT prevention or treatment) is essential to balance the risk of bleeding and clotting.
