Nokea
Which skin disorder most closely resembles and mimics dandruff?
- A. Lice infestation
- B. Scabies
- C. Dermatitis
- D. Acne vulgaris
Correct Answer: C
Rationale: Dermatitis can closely resemble and mimic dandruff due to similar symptoms like flaking and itching. Lice infestation (choice A) is characterized by the presence of lice and their eggs attached to the hair shaft, different from dandruff. Scabies (choice B) is a contagious skin condition caused by mites, presenting as burrows, rashes, and intense itching, not typically resembling dandruff. Acne vulgaris (choice D) is a skin condition involving hair follicles and sebaceous glands, manifesting as pimples and inflammation, which is distinct from dandruff.

Your long-term care patient has chronic pain and at this point in time, the patient needs increasing dosages to adequately control this pain. What is this patient most likely affected by?
- A. Drug addiction
- B. Drug interactions
- C. Drug side effects
- D. Drug tolerance
Correct Answer: D
Rationale: The correct answer is D: Drug tolerance. When a patient needs increasing dosages to achieve the same pain relief, it indicates the development of drug tolerance. This means the body has adapted to the drug, requiring higher doses to produce the same effect. Choice A, drug addiction, is incorrect because drug addiction involves a psychological and physical dependence on the drug, which is not described in the scenario. Choice B, drug interactions, is incorrect as it refers to the effects when multiple drugs interact with each other, not the situation described. Choice C, drug side effects, is also incorrect as it pertains to the unintended effects of a drug, not the need for higher doses to control pain.
Select the stage of shock that is accurately paired with its characteristic.
- A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
- B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
- C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
- D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.
Correct Answer: C
Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.
A nurse is assessing a client with a suspected diagnosis of hypocalcemia. Which of the following clinical manifestations would the nurse expect to note in the client?
- A. Twitching
- B. Positive Trousseau's sign
- C. Hyperactive bowel sounds
- D. Hyperactive deep tendon reflexes
Correct Answer: A
Rationale: The correct answer is A: Twitching. Hypocalcemia often presents with neuromuscular irritability, leading to manifestations such as twitching. Trousseau's sign is actually a positive indicator of hypocalcemia, not negative, making choice B incorrect. Hypoactive bowel sounds are not typically associated with hypocalcemia, making choice C incorrect. Similarly, hypoactive deep tendon reflexes are not a common finding in hypocalcemia, making choice D incorrect.
Select the stage of viral hepatitis that is accurately paired with its characteristic(s).
- A. The prodromal stage: Jaundice begins
- B. The icteric stage: Flu-like symptoms occur
- C. The pre-icteric stage: Elevated urine bilirubin levels
- D. The post-icteric stage: Jaundice and dark urine occur
Correct Answer: D
Rationale: The post-icteric stage of viral hepatitis is accurately described as the stage where jaundice and dark urine occur due to the accumulation of bilirubin. The resolution of jaundice and normalization of urine color are seen in this stage. Choices A, B, and C are incorrect. In the prodromal stage, symptoms like fatigue and malaise appear before jaundice. The icteric stage is characterized by jaundice, not flu-like symptoms. The pre-icteric stage does not typically involve elevated urine bilirubin levels, as this occurs after the icteric stage.
Which of the following foods enhances the absorption of an iron supplement?
- A. Orange juice
- B. Green beans
- C. Fortified milk
- D. Baked potato
Correct Answer: A
Rationale: The correct answer is Orange juice. Orange juice enhances the absorption of an iron supplement due to its high vitamin C content. Vitamin C helps in the absorption of non-heme iron, the type of iron found in plant-based foods and iron supplements. Green beans, fortified milk, and baked potato do not have the same level of vitamin C as orange juice, making them less effective in enhancing iron absorption.
