How does cancer affect pain tolerance in elderly clients?

Correct Answer: B

Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.

Correct Answer: C

Rationale: For a 4-year-old client struggling to sleep in the hospital, the best nursing intervention is to identify the child's home bedtime rituals and follow them. Preschool-age children often have specific bedtime routines that provide comfort and promote sleep. This familiarity can help create a sense of security in an unfamiliar hospital environment. Choice A, turning off the room light and closing the door, may increase the child's fear of the dark and being alone. Choice B, engaging the child in calming activities before bedtime, is a better choice than tiring them with play exercises. Choice D, encouraging relaxation techniques like deep breathing exercises, although helpful, may not be as effective as following the child's familiar bedtime routines.

Correct Answer: C

Rationale: The correct answer is 6 liters/minute. When a client needs oxygen therapy, the highest flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Higher flow rates must be delivered by a mask. Choices A, B, and D are incorrect because they suggest flow rates that exceed what can be effectively delivered through a nasal cannula.

Correct Answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

Correct Answer: D

Rationale: Huntington's chorea is a neurological disorder characterized by writhing, twisting movements of the face and limbs, known as chorea. Epilepsy is characterized by seizures, not writhing, twisting movements. Parkinson's disease presents with tremors, rigidity, and bradykinesia, not writhing, twisting movements. Multiple sclerosis affects the central nervous system but does not typically involve writhing, twisting movements. Therefore, the correct answer is Huntington's chorea as it specifically manifests with these characteristic movements.

Correct Answer: B

Rationale: The correct answer is 'Toddlers.' Toddlers are at the highest risk of unintentional poisoning due to their natural curiosity, explorative behavior, and lack of awareness of potential dangers. Infants are typically closely monitored, teens are more aware of risks, and adults generally have better judgment and understanding of hazardous substances, making them less susceptible to unintentional poisoning. Therefore, toddlers, being inquisitive and unaware of risks, are the most vulnerable group in terms of unintentional poisoning incidents.

Correct Answer: A

Rationale: When a client is experiencing a seizure and their blood oxygen saturation drops, the priority action for the nurse is to open the airway. Ensuring a clear airway is essential to maintain oxygenation during a seizure episode. Administering oxygen may be necessary but is secondary to ensuring a patent airway. Suctioning the client should only be done if there is an airway obstruction. Checking for breathing is important, but opening the airway takes precedence to support ventilation and oxygenation.

Correct Answer: A

Rationale: Cushing's syndrome is characterized by increased cortisol levels due to the overproduction of cortisol by the adrenal glands. This excess cortisol can lead to various symptoms and complications. Addison's disease is associated with decreased cortisol levels as it results from adrenal insufficiency, making it an incorrect choice in this context. Renal failure and congestive heart failure are not typically linked to abnormal cortisol levels, further indicating that they are not the conditions where increased cortisol levels are found.

Correct Answer: C

Rationale: Rifampin has the unusual effect of turning body fluids an orange color. Soft contact lenses might become permanently stained. Clients should be taught about these side effects to avoid unnecessary concern. Option A is incorrect as Rifampin does not cause the urine to turn blue. Option B is incorrect as the client is not infectious to others due to taking Rifampin for prophylaxis. Option D is incorrect as Rifampin does not cause the skin to take on a crimson glow.
