Final Exam Pathophysiology
1. A child is experiencing difficulty with chewing and swallowing. The nurse knows that which cells may be innervating specialized gut-related receptors that provide taste and smell?
- A. Special somatic afferent fibers
- B. General somatic afferents
- C. Special visceral afferent cells
- D. General visceral afferent neurons
Correct answer: C
Rationale: The correct answer is C: Special visceral afferent cells. These cells are responsible for innervating taste and smell receptors related to the gut. Special somatic afferent fibers (choice A) are involved in sensations like touch and proprioception, not taste and smell. General somatic afferents (choice B) carry sensory information from the skin and musculoskeletal system, not taste and smell. General visceral afferent neurons (choice D) transmit sensory information from internal organs, but not specifically related to taste and smell sensations.
2. Which pathophysiologic process causes the decreased glomerular filtration rate in a patient with acute glomerulonephritis?
- A. Decreased renal-induced constriction of the renal arteries
- B. Immune complex deposition, increased capillary permeability, and cellular proliferation
- C. Necrosis of 70% or more of the nephrons secondary to increased kidney interstitial hydrostatic pressure
- D. Scar tissue formation throughout the proximal convoluted tubule secondary to toxin-induced collagen synthesis
Correct answer: B
Rationale: The correct answer is B: Immune complex deposition, increased capillary permeability, and cellular proliferation. In acute glomerulonephritis, immune complexes deposit in the glomerulus, leading to inflammation, increased capillary permeability, and cellular proliferation. These processes collectively reduce the glomerular filtration rate. Choices A, C, and D do not accurately describe the pathophysiologic process in acute glomerulonephritis. Decreased renal-induced constriction of the renal arteries, necrosis of nephrons due to increased kidney interstitial hydrostatic pressure, and scar tissue formation in the proximal convoluted tubule are not the primary mechanisms responsible for the decreased filtration rate in this condition.
3. A male patient with benign prostatic hyperplasia (BPH) is being treated with tamsulosin (Flomax). What should the nurse include in the teaching plan for this patient?
- A. Avoid lying down after taking the medication.
- B. Take the medication with meals.
- C. Report any side effects such as dizziness or fainting.
- D. Take the medication at bedtime.
Correct answer: C
Rationale: The correct answer is C: 'Report any side effects such as dizziness or fainting.' Patients taking tamsulosin should be advised to report any side effects, such as dizziness or fainting, which can occur due to orthostatic hypotension. Choices A, B, and D are incorrect because avoiding lying down after taking the medication, taking it with meals, or at bedtime are not specific teaching points related to the potential side effects of tamsulosin.
4. During a flu shot clinic, one of the questions the student nurse asks relates to whether the client has a history of Guillain-Barré syndrome. The client asks, 'What is that?' How should the nursing student reply?
- A. A type of paralysis that affects movement on both sides of the body. It may even involve the respiratory muscles.
- B. Swelling of your arm where you got your flu shot and maybe your eyes and lips had some swelling as well.
- C. A degenerative disease where you have trouble walking without the help of a cane or walker.
- D. Influenza-like illness where you had fever and chills for 2 to 3 days after your last flu shot.
Correct answer: A
Rationale: The correct answer is A because Guillain-Barré syndrome is an acute immune-mediated polyneuropathy that can lead to paralysis affecting movement on both sides of the body, and in severe cases, involving the respiratory muscles. Choice B is incorrect as it describes local swelling, not the systemic effects of Guillain-Barré syndrome. Choice C is incorrect as it describes a degenerative disease affecting mobility, not an acute immune-mediated condition like Guillain-Barré syndrome. Choice D is incorrect as it describes flu-like symptoms following a flu shot, which is not the same as Guillain-Barré syndrome.
5. A 43-year-old man has tested positive for systemic candidiasis, and the care team has decided on IV fluconazole as a first-line treatment. When administering this medication, the nurse should
- A. administer the drug with lactated Ringer's.
- B. infuse the drug no faster than 200 mg/h.
- C. avoid administering the drug through a peripheral IV.
- D. administer prophylactic heparin prior to the fluconazole.
Correct answer: C
Rationale: When administering IV fluconazole, the nurse should avoid administering the drug through a peripheral IV. Fluconazole is known to cause phlebitis and tissue irritation if infused through a peripheral IV line. It is recommended to administer fluconazole through a central venous catheter to reduce the risk of complications. Choices A, B, and D are incorrect as there is no specific recommendation to administer the drug with lactated Ringer's, infuse it at a particular rate, or administer prophylactic heparin prior to fluconazole in this scenario.
