ATI Pathophysiology
1. A 45-year-old diabetic male is experiencing erectile dysfunction. If his erectile dysfunction is caused by the nervous system, then the nurse can educate the client that the venous blood supply to the penis is controlled by:
- A. Sympathetic nerves.
- B. Parasympathetic nerves.
- C. Somatic nerves.
- D. Spinal reflexes.
Correct answer: B
Rationale: Erectile function is primarily controlled by the parasympathetic nervous system, which facilitates the dilation of blood vessels in the penis. The parasympathetic nerves are responsible for vasodilation in the penis, allowing blood to enter and creating an erection. Sympathetic nerves, on the other hand, are responsible for ejaculation by causing contraction of the muscles around the vas deferens. Somatic nerves are involved in sensation and movement, not specifically in controlling blood supply to the penis. Spinal reflexes can play a role in the erectile process, but they are not directly responsible for controlling the venous blood supply.
2. A patient is taking a statin for hyperlipidemia. What important instruction should the nurse provide to the patient?
- A. Take the medication at night to avoid muscle pain.
- B. Take the medication in the morning to ensure it works throughout the day.
- C. Avoid consuming alcohol while taking this medication.
- D. Take the medication with a high-fat meal to increase absorption.
Correct answer: A
Rationale: The correct answer is to instruct the patient to take the medication at night to avoid muscle pain. Statins are known to potentially cause muscle pain or weakness; taking the medication at night can help reduce the incidence of these side effects. Option B is incorrect because the timing of statin administration is not related to its effectiveness throughout the day. Option C is a general precaution when taking medications but not the most important instruction specific to statins. Option D is incorrect as taking the medication with a high-fat meal can actually decrease its absorption.
3. Which information would indicate more teaching is needed regarding hypersensitivity reactions? Type _______ hypersensitivity reactions involve an antibody response.
- A. I
- B. II
- C. III
- D. IV
Correct answer: D
Rationale: The correct answer is D: Type IV hypersensitivity reactions involve cell-mediated immunity, not an antibody response. This question tests knowledge of hypersensitivity reactions and their classification. Type I hypersensitivity reactions involve IgE antibodies, Type II involves IgG or IgM antibodies, and Type III involves immune complex deposition. Type IV hypersensitivity reactions are delayed and involve T cells, not antibodies. Therefore, if a person believes that Type IV hypersensitivity reactions involve an antibody response, more teaching is required.
4. A student is feeling inside her backpack to find her mobile phone. There are a number of other items in the bag other than the phone. The nurse knows that which term best describes one's ability to sense the shape and size of an object in the absence of visualization?
- A. Stereognosis
- B. Graphesthesia
- C. Proprioception
- D. Kinesthesia
Correct answer: A
Rationale: Stereognosis is the correct answer. It refers to the ability to recognize objects by touch, specifically determining their shape and size without relying on visual cues. Graphesthesia, on the other hand, is the ability to recognize symbols or numbers traced on the skin. Proprioception involves the awareness of body position and movement. Kinesthesia relates to the perception of body movement.
5. Seizures are diagnosed by which of the following?
- A. Electroencephalogram (EEG) and ECG
- B. Seizure symptoms and complete blood count (CBC)
- C. Seizure symptoms and electrocardiogram (ECG)
- D. Seizure symptoms and EEG
Correct answer: D
Rationale: Seizures are most accurately diagnosed by EEG, which measures brain activity. Choice A is incorrect as ECG (electrocardiogram) measures heart activity, not brain activity. Choice B is incorrect as CBC (complete blood count) is a blood test and not used to diagnose seizures. Choice C is incorrect as an ECG (electrocardiogram) also measures heart activity, not brain activity, and is not the primary diagnostic tool for seizures.
