1. Inflammatory exudates are a combination of several types. Which of the following exudates is composed of a large accumulation of leukocytes?
- A. Serous
- B. Purulent
- C. Fibrinous
- D. Hemorrhagic
Correct answer: B
Rationale: The correct answer is B: Purulent. Purulent exudates, or pus, consist primarily of leukocytes and dead cells, indicating a bacterial infection. Serous exudates contain a thin, watery fluid with few leukocytes. Fibrinous exudates are rich in fibrin and are commonly seen in severe inflammation. Hemorrhagic exudates contain red blood cells due to blood vessel damage.
2. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What critical information should the nurse provide during patient education?
- A. Tamoxifen may increase the risk of venous thromboembolism, so patients should be educated about the signs and symptoms of blood clots.
- B. Tamoxifen may decrease the risk of osteoporosis, so adequate calcium intake is important.
- C. Tamoxifen may cause weight gain, so patients should monitor their diet.
- D. Tamoxifen may increase the risk of breast cancer, so regular mammograms are essential.
Correct answer: A
Rationale: When a patient is prescribed tamoxifen, a critical piece of information that the nurse should provide during patient education is that tamoxifen may increase the risk of venous thromboembolism. Therefore, patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur. Choice B is incorrect because tamoxifen does not decrease the risk of osteoporosis. Choice C is incorrect as weight gain is a possible side effect of tamoxifen, but it is not a critical piece of information compared to the risk of venous thromboembolism. Choice D is incorrect because tamoxifen is actually used to treat breast cancer, not increase its risk.
3. A client with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons. Which process will accompany the actions of the neurotransmitter in a chemical synapse?
- A. Two-way communication between neurons is permitted, in contrast to the one-way communication in electrical synapses.
- B. Communication between a neuron and the single neuron it is connected with will be facilitated.
- C. The neurotransmitter will cross gap junctions more readily.
- D. More neurotransmitters will cross the synaptic cleft and bond with postsynaptic receptors.
Correct answer: D
Rationale: When serotonin levels increase, more neurotransmitters will cross the synaptic cleft and bind with postsynaptic receptors, facilitating enhanced communication. Option A is incorrect because chemical synapses, unlike electrical synapses, are unidirectional. Option B is incorrect because neurotransmitters impact communication with multiple neurons, not just a single connected neuron. Option C is incorrect because neurotransmitters cross the synaptic cleft, not gap junctions.
4. Which of the following describes inflammation of the bladder lining?
- A. Incontinence
- B. Pyelonephritis
- C. Urinary calculi
- D. Cystitis
Correct answer: D
Rationale: The correct answer is D, Cystitis. Cystitis specifically refers to the inflammation of the bladder lining. Choice A, Incontinence, refers to the loss of bladder control and is not related to inflammation. Choice B, Pyelonephritis, is the inflammation of the kidney and renal pelvis, not the bladder lining. Choice C, Urinary calculi, refers to the formation of stones in the urinary tract and is not related to bladder inflammation.
5. Which of the following mediates humoral immunity?
- A. Natural killer cells
- B. T cells
- C. B cells
- D. Neutrophils
Correct answer: C
Rationale: Humoral immunity is mediated by B cells, not natural killer cells, T cells, or neutrophils. B cells are responsible for producing antibodies, which are essential components of humoral immunity.
