A patient presents with gradual-onset memory loss, confusion, and difficulty with complex tasks such as managing finances and planning. Over time, the patient develops disorientation to time and place and requires assistance with activities of daily living. Which of the following neurological conditions is most likely responsible for these symptoms?

Correct Answer: A

Rationale: The patient's presentation of gradual-onset memory loss, confusion, difficulty with complex tasks, disorientation, and functional decline are all classic features of Alzheimer's disease. Alzheimer's disease is a progressive neurodegenerative disorder characterized by the accumulation of abnormal protein deposits in the brain, leading to widespread neuronal damage and cognitive decline. As the disease progresses, patients typically experience worsening memory loss, cognitive impairment, and deficits in activities of daily living, ultimately requiring full-time care and assistance. Other neurodegenerative diseases such as Parkinson's disease, Huntington's disease, and frontotemporal dementia may present with cognitive impairment and behavioral changes, but the specific constellation of symptoms described in the case is most indicative of Alzheimer's disease.

Correct Answer: D

Rationale: The given clinical presentation of chest pain that worsens with swallowing and is relieved by leaning forward along with diffuse ST-segment elevation on an ECG is highly suggestive of pericarditis. Pericarditis is the inflammation of the pericardium, the thin sac surrounding the heart. The symptoms of pericarditis can mimic those of myocardial infarction (heart attack) but can also be differentiated by certain characteristics such as the described positional chest pain, which is worsened by swallowing and relieved by leaning forward.

Correct Answer: B

Rationale: Pain is best described as a subjective unpleasant experience because it is unique to each individual and is influenced by a variety of factors including emotional, psychological, and cultural elements. Pain cannot be objectively measured or quantified, and therefore it is considered a subjective experience that is reported by the person experiencing it. This is why pain is often assessed using self-report scales and tools to capture the individual's perception of their pain intensity and quality.

Correct Answer: A

Rationale: The presentation described in the question is classic for basal cell carcinoma (BCC). BCC typically presents as multiple, flesh-colored, papular lesions with a central dell (resembling a pearl-like appearance) on sun-exposed areas such as the face and trunk. These lesions are known to bleed easily upon minor trauma and tend to increase in number over time. BCC is the most common type of skin cancer, often triggered by sun exposure. On the other hand, seborrheic keratosis (choice C) presents as benign, pigmented, stuck-on, waxy, or warty lesions with a rough surface, true bumpy appearance. Squamous cell carcinoma (choice B) usually presents as a scaly, erythematous, rapidly growing nodule, ulcer, or plaque. Actinic keratosis (choice D) presents as rough, scaly patches on sun-exposed areas that can progress to

Correct Answer: D

Rationale: The herbal medicine recommended by the Department of Health for cough is Lagundi (scientific name: Vitex negundo). Lagundi has been found to have properties that can help relieve cough, asthma, and other respiratory conditions. It has been traditionally used as a natural remedy for these purposes and has gained recognition for its effectiveness in managing cough symptoms. Additionally, Lagundi is also known for its anti-inflammatory and analgesic properties, further supporting its use in addressing respiratory ailments.

Correct Answer: B

Rationale: Option B, "Maintaining professional boundaries helps protect both patients and nurses," indicates an understanding of the importance of professional boundaries in nursing practice. Professional boundaries define the limits of the nurse-patient relationship and help ensure that interactions are safe, therapeutic, and based on the patient's best interest. By maintaining these boundaries, nurses can uphold ethical standards, prevent harm, and maintain trust with patients. It also helps prevent issues such as transference, countertransference, and breaches of confidentiality. Overall, understanding and respecting professional boundaries are essential for promoting the well-being of both patients and healthcare providers.

Correct Answer: B

Rationale: Spironolactone is a potassium-sparing diuretic commonly used in the management of heart failure. One of the significant side effects of spironolactone is hyperkalemia, which is an elevated level of potassium in the bloodstream. Spironolactone works by blocking the action of aldosterone, a hormone that regulates potassium and sodium balance in the body. By inhibiting aldosterone, spironolactone reduces potassium excretion in the urine, leading to potential accumulation of potassium in the body.

Correct Answer: C

Rationale: Among the given options, teratoma (dermoid cyst) is the most common type of ovarian tumor in women of reproductive age. Dermoid cysts are a type of ovarian teratoma that contains tissues derived from the ectoderm (skin), mesoderm (bone, muscle), and endoderm (mucous membranes). They are usually benign and can contain a variety of elements such as hair, teeth, bone, and sebaceous material. Serous cystadenomas and mucinous cystadenomas are more commonly seen in older women, whereas endometriomas are typically associated with endometriosis rather than being the most common ovarian tumor type in women of reproductive age.

Correct Answer: B

Rationale: Monitoring oxygen saturation with pulse oximetry is essential for preventing respiratory depression in a patient prescribed an opioid analgesic. Opioid analgesics can suppress the respiratory drive, leading to respiratory depression. By constantly monitoring the patient's oxygen saturation levels with pulse oximetry, nurses can promptly detect any signs of respiratory depression and intervene early to prevent serious complications. This allows for timely adjustments in the medication dosage or administration of other supportive measures to maintain adequate oxygenation and prevent respiratory compromise. Administering naloxone prophylactically may be necessary in case of an opioid overdose but is not typically done as a preventive measure. Encouraging deep breathing exercises can help prevent respiratory complications postoperatively but may not be sufficient in the presence of opioid-induced respiratory depression. Administering bronchodilators as needed is not directly related to preventing respiratory depression caused by opioid analgesics.
