Nokea
A patient presents with intensely pruritic, linear burrows on the web spaces of the hands and wrists. The patient reports a history of close contact with an individual diagnosed with a similar condition. Which of the following conditions is most likely responsible for this presentation?
- A. Scabies
- B. Pediculosis (lice infestation)
- C. Tinea corporis (ringworm)
- D. Contact dermatitis
Correct Answer: A
Rationale: The correct answer is A: Scabies. This presentation is classic for scabies infestation caused by the Sarcoptes scabiei mite. The intensely pruritic linear burrows are pathognomonic. Close contact with an individual with scabies increases the likelihood of transmission. The other choices, B: Pediculosis, C: Tinea corporis, and D: Contact dermatitis, do not typically present with linear burrows on the hands and wrists. Pediculosis presents with lice infestation, Tinea corporis with circular lesions, and contact dermatitis with erythema and edema.

Korino has been using meperidine and codeine for personal consumption. Which of the following does the nurse understand as the physiologic effect of these drugs?
- A. Increases sexual stimulation.
- B. Relieves pain by increasing pain threshold.
- C. Decrease craving for alcoholic intake.
- D. Heightens concentration and alertness
Correct Answer: B
Rationale: The correct answer is B: Relieves pain by increasing pain threshold. Meperidine and codeine are opioid analgesics that work by binding to opioid receptors in the brain and spinal cord, thus increasing the pain threshold and reducing the perception of pain. This leads to pain relief without necessarily affecting sexual stimulation (choice A), craving for alcohol (choice C), or concentration/alertness (choice D). The primary physiological effect of these drugs is to modulate the perception of pain, making choice B the most appropriate answer in this context.
A patient presents with chest pain, dyspnea, and hemoptysis. A ventilation-perfusion (V/Q) scan reveals a mismatched defect. Which cardiovascular disorder is most likely responsible for these symptoms?
- A. Pulmonary embolism
- B. Pericarditis
- C. Acute myocardial infarction
- D. Aortic dissection
Correct Answer: A
Rationale: The correct answer is A: Pulmonary embolism. This is the most likely cause of the symptoms based on the presentation of chest pain, dyspnea, hemoptysis, and a mismatched defect on the V/Q scan. A pulmonary embolism occurs when a blood clot travels to the lungs, causing a blockage in the pulmonary artery. This can lead to symptoms like chest pain, shortness of breath, and coughing up blood. The V/Q scan showing a mismatched defect indicates a ventilation-perfusion mismatch, which is a classic finding in pulmonary embolism. Pericarditis (B), acute myocardial infarction (C), and aortic dissection (D) typically present with different sets of symptoms and do not match the V/Q scan findings in this case.
A postpartum client who delivered via cesarean section expresses discomfort when ambulating and performing activities of daily living. What nursing intervention should be prioritized to promote optimal recovery?
- A. Encouraging early ambulation and progressive activity as tolerated
- B. Administering oral analgesics on a fixed schedule around the clock
- C. Restricting movement to prevent disruption of the incision site
- D. Applying heat packs to the incision site for pain relief
Correct Answer: A
Rationale: Encouraging early ambulation and progressive activity as tolerated is the most appropriate nursing intervention to promote optimal recovery for a postpartum client who delivered via cesarean section. Early ambulation helps prevent complications such as blood clots, pneumonia, and constipation. It also promotes circulation and facilitates healing by reducing the risk of postoperative complications. Progressive activity helps the client regain strength, mobility, and independence, which are essential for a speedy recovery. Restoring normal movement will also help decrease discomfort and improve the client's overall well-being. In contrast, restricting movement may lead to complications and delayed recovery. Administering oral analgesics as needed is important for pain management, but promoting early ambulation is essential for optimal recovery. Heat packs should not be applied to the incision site as they can increase the risk of infection and interfere with proper wound healing.
Which of the following dental conditions is characterized by the wearing away of tooth structure due to friction from external sources such as toothbrushing or abrasive toothpaste?
- A. Dental caries
- B. Attrition
- C. Abrasion
- D. Erosion
Correct Answer: C
Rationale: The correct answer is C: Abrasion. Abrasion is the wearing away of tooth structure due to friction from external sources like toothbrushing or abrasive toothpaste. Dental caries (A) refers to tooth decay caused by bacteria. Attrition (B) is the wearing down of tooth structure due to tooth-to-tooth contact. Erosion (D) is the loss of tooth structure from acid attacks, not friction. Therefore, option C is the most fitting choice based on the description given.
A Patients to take regularly Lithium after discharged. The MOST important information to impart to the patient and his family is that the patient should
- A. not eat foods which has high tyramine content like cheese, wine, liver
- B. limit his fluid intake
- C. have a limited intake of sodium
- D. have an adequate intake of sodium
Correct Answer: C
Rationale: The correct answer is C, to have a limited intake of sodium. Lithium can lead to increased sodium levels in the body, potentially causing toxicity. By limiting sodium intake, the patient can maintain a balance and prevent adverse effects. Choice A is incorrect as tyramine content is not directly related to lithium intake. Choice B is incorrect as fluid intake does not have a significant impact on lithium levels. Choice D is incorrect because an adequate intake of sodium can lead to worsening lithium toxicity.
