Pathophysiology Practice Exam
1. In a patient with renal failure secondary to an overdose of a nephrotoxic drug, which assessment findings would the nurse recognize as being most suggestive of impaired erythropoiesis?
- A. Frequent infections and low neutrophil levels
- B. Fatigue and increased heart rate
- C. Agitation and changes in cognition
- D. Increased blood pressure and peripheral edema
Correct answer: A
Rationale: Impaired erythropoiesis refers to a decreased production of red blood cells. This can lead to anemia, resulting in symptoms like fatigue and increased heart rate (Choice B). However, the question specifically asks about assessment findings suggestive of impaired erythropoiesis. In this context, frequent infections and low neutrophil levels (Choice A) are more directly related to impaired erythropoiesis due to the impact of anemia on the immune system. Frequent infections are common in anemia due to a compromised immune response, and low neutrophil levels can be seen in conditions of impaired erythropoiesis. Agitation and changes in cognition (Choice C) are more indicative of neurological issues, while increased blood pressure and peripheral edema (Choice D) are commonly associated with renal failure but not specifically related to impaired erythropoiesis.
2. 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.
3. When administering an immunization, which of the following medications should be available?
- A. Diphenhydramine (Benadryl)
- B. Hydroxyzine (Vistaril)
- C. Physostigmine
- D. Epinephrine
Correct answer: D
Rationale: When administering an immunization, it is essential to have epinephrine available in case of an allergic reaction such as anaphylaxis. Epinephrine is the medication of choice for treating severe allergic reactions due to its ability to reverse the symptoms rapidly. Diphenhydramine and hydroxyzine are antihistamines that can help manage mild allergic reactions but are not the primary medications for severe reactions like anaphylaxis. Physostigmine is not indicated for managing allergic reactions and is used for specific conditions such as anticholinergic toxicity.
4. A patient is administered a nucleotide reverse transcriptase inhibitor in combination with a nonnucleotide reverse transcriptase inhibitor. What is the main rationale for administering these medications together?
- A. They improve treatment adherence.
- B. They reduce the duration of illness.
- C. They exhibit synergistic antiviral effects.
- D. They prevent opportunistic infections.
Correct answer: C
Rationale: The main rationale for administering a nucleotide reverse transcriptase inhibitor in combination with a nonnucleotide reverse transcriptase inhibitor is that they exhibit synergistic antiviral effects when used together. This combination enhances their antiviral activity against HIV by targeting different steps in the viral replication cycle. Choice A is incorrect because the rationale for combining these medications is based on their antiviral effects, not treatment adherence. Choice B is incorrect because the primary purpose of combination therapy is not to reduce the duration of illness but to improve treatment efficacy. Choice D is incorrect as the main focus of this combination is not on preventing opportunistic infections but on directly targeting the HIV virus.
5. What common symptom should be assessed in individuals with immunodeficiency?
- A. Anemia
- B. Recurrent infections
- C. Hypersensitivity
- D. Autoantibody production
Correct answer: B
Rationale: Recurrent infections are a hallmark symptom of immunodeficiency. Individuals with impaired immune systems are more susceptible to recurrent infections due to their compromised ability to fight off pathogens. Anemia (Choice A) is not a direct symptom of immunodeficiency but can be a consequence of chronic diseases. Hypersensitivity (Choice C) refers to exaggerated immune responses rather than impaired immune function. Autoantibody production (Choice D) is not typically a primary symptom of immunodeficiency but may be seen in certain autoimmune conditions.
