ATI Pathophysiology Exam 2

1. A patient has acute respiratory failure (ARF). Which of the following would the nurse expect to find?

A. Alkalosis and hyperventilation
B. Hypoxemia and hypercapnia
C. Alkalosis and high potassium
D. Elevated sodium and acidosis

Correct answer: B

Rationale: In acute respiratory failure, hypoxemia (low blood oxygen) and hypercapnia (high blood carbon dioxide) are commonly observed. Choice A is incorrect because alkalosis (high pH) and hyperventilation are not typically seen in acute respiratory failure. Choice C is incorrect as it mentions alkalosis and high potassium, which are not characteristic of acute respiratory failure. Choice D is also incorrect because elevated sodium and acidosis are not typically associated with acute respiratory failure.

2. A 52-year-old male patient is taking finasteride (Proscar) for benign prostatic hyperplasia (BPH). What patient teaching should the nurse provide?

A. Take the medication with food.
B. Avoid taking NSAIDs while on this medication.
C. Avoid driving or operating heavy machinery while taking this medication.
D. Women who are or may become pregnant should not handle crushed or broken tablets.

Correct answer: D

Rationale: The correct answer is D. Finasteride, used for BPH, can be harmful to a developing male fetus. Therefore, women who are or may become pregnant should not handle crushed or broken tablets to avoid potential absorption through the skin. Choice A is incorrect as finasteride can be taken with or without food. Choice B is incorrect because there is no specific interaction between finasteride and NSAIDs mentioned. Choice C is incorrect as finasteride does not typically cause drowsiness or impair mental alertness.

3. A 52-year-old has made an appointment with his primary care provider and has reluctantly admitted that his primary health concern is erectile dysfunction (ED). He describes the problem as increasing in severity and consequent distress. Which of the nurse's assessment questions is most likely to address a common cause of ED?

A. “How would you describe your overall health status?”
B. “Are you taking any medications for high blood pressure?”
C. “How has this issue been impacting your relationship?”
D. “Have you experienced any recent injuries?”

Correct answer: B

Rationale: In the context of erectile dysfunction (ED), medication use is a crucial factor to consider. Many medications, including those used for high blood pressure, can contribute to ED as a side effect. Asking about medication use, particularly for conditions like high blood pressure, can help identify a common cause of ED. Choices A, C, and D do not directly address potential causes related to medication use, making them less likely to reveal a common underlying issue for ED in this case.

4. A 30-year-old male has been brought to the emergency department by his wife because of a severe headache, nausea, vomiting, and fever. A lumbar puncture is performed, and cerebrospinal fluid (CSF) analysis reveals a high protein count, low glucose, and numerous polymorphonuclear leukocytes (PMNs). Which organism is the most likely cause of these findings?

A. Streptococcus pneumoniae
B. Neisseria meningitidis
C. Escherichia coli
D. Listeria monocytogenes

Correct answer: A

Rationale: The cerebrospinal fluid (CSF) analysis findings of high protein count, low glucose, and numerous polymorphonuclear leukocytes (PMNs) are classic for bacterial meningitis. Among the choices, Streptococcus pneumoniae is the most likely cause in this case. Streptococcus pneumoniae is a common cause of bacterial meningitis in adults, especially presenting with symptoms such as severe headache, nausea, vomiting, and fever. Neisseria meningitidis is another common cause of bacterial meningitis but is more frequently associated with a different CSF profile. Escherichia coli is a common cause of neonatal meningitis, not typically seen in a 30-year-old male. Listeria monocytogenes is more commonly associated with meningitis in immunocompromised individuals and neonates, and typically presents differently in CSF analysis.

5. A 74-year-old woman states that many of her peers underwent hormone replacement therapy (HRT) in years past. The woman asks the nurse why her primary care provider has not yet proposed this treatment for her. What fact should underlie the nurse's response to the woman?

A. The risks of stroke and breast cancer are unacceptably high in women taking HRT.
B. HRT was found to cause mood disturbances in many women who used it long term.
C. HRT was found to be a significant risk factor for bone fractures and osteoporosis.
D. The risks of chronic obstructive pulmonary disease were found to be significantly higher in women using HRT.

Correct answer: A

Rationale: The correct answer is A because the main reason HRT is not recommended for all women is due to the increased risks of stroke and breast cancer associated with its use. Hormone replacement therapy (HRT) has been linked to an elevated risk of stroke and breast cancer, which outweigh its potential benefits for many individuals. Choices B, C, and D are incorrect as they do not address the primary concerns regarding HRT use. While HRT can indeed cause mood disturbances and may affect bone health, the significant risks of stroke and breast cancer are the primary reasons why healthcare providers may choose not to recommend HRT for some women.
