1. A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?
- A. Inflammation of the synovial membrane.
- B. Degeneration of the cartilage in the joint.
- C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
- D. Formation of uric acid crystals in the joint space.
Correct answer: C
Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.
2. A client with hyperthyroidism is prescribed methimazole. Which adverse effect should the nurse monitor for?
- A. Agranulocytosis
- B. Hypoglycemia
- C. Bradycardia
- D. Hypercalcemia
Correct answer: A
Rationale: The correct answer is Agranulocytosis. Methimazole, used to treat hyperthyroidism, can lead to agranulocytosis, a severe decrease in white blood cells. This condition increases the risk of infections and requires immediate medical attention. Hypoglycemia (choice B) is not a common adverse effect of methimazole. Bradycardia (choice C) is unlikely as methimazole tends to have minimal effects on heart rate. Hypercalcemia (choice D) is not associated with methimazole use.
3. When planning care for a client newly diagnosed with open-angle glaucoma, the nurse identifies a priority nursing problem of visual sensory/perceptual alterations. This problem is based on which etiology?
- A. Limited eye movement.
- B. Decreased peripheral vision.
- C. Blurred distance vision.
- D. Photosensitivity.
Correct answer: B
Rationale: The correct answer is B: Decreased peripheral vision. In open-angle glaucoma, decreased peripheral vision is a characteristic symptom resulting from increased intraocular pressure. This visual impairment can lead to sensory/perceptual alterations. Choice A, limited eye movement, is not directly associated with the pathophysiology of open-angle glaucoma. Choice C, blurred distance vision, is more commonly seen in conditions like myopia or presbyopia. Choice D, photosensitivity, is not a typical manifestation of open-angle glaucoma and is more commonly associated with conditions like migraines or certain medications.
4. To assess the quality of an adult client’s pain, what approach should the nurse use?
- A. Ask the client to rate the pain on a scale of 1 to 10.
- B. Ask the client to describe the pain.
- C. Observe the client’s nonverbal cues.
- D. Determine the client’s pain tolerance.
Correct answer: B
Rationale: The correct approach for assessing the quality of an adult client's pain is to ask the client to describe the pain. By doing so, the nurse gains valuable information about the quality, location, and nature of the pain directly from the client. This approach allows for a more comprehensive understanding of the pain experience. Choice A, asking the client to rate the pain on a scale of 1 to 10, focuses more on intensity rather than quality. Choice C, observing the client's nonverbal cues, can provide additional information but may not fully capture the client's subjective experience of pain. Choice D, determining the client's pain tolerance, is not directly related to assessing the quality of pain but rather to how much pain a client can endure.
5. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?
- A. The client is hyperventilating due to anxiety.
- B. The hypoxic drive was reduced by the oxygen therapy.
- C. The client is experiencing respiratory alkalosis.
- D. The client is experiencing metabolic acidosis.
Correct answer: B
Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.
