ATI Pathophysiology Final Exam
1. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What important 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 cause weight gain, so patients should monitor their diet.
- C. Tamoxifen may decrease the risk of osteoporosis, so patients should ensure adequate calcium intake.
- D. Tamoxifen may increase the risk of breast cancer, so regular mammograms are essential.
Correct answer: A
Rationale: The correct answer is A. Tamoxifen increases the risk of venous thromboembolism, a serious side effect, so patients should be educated about the signs and symptoms of blood clots. This information is crucial as early recognition and prompt treatment of blood clots can prevent complications. Choices B, C, and D are incorrect because tamoxifen is not associated with causing weight gain, decreasing the risk of osteoporosis, or increasing the risk of breast cancer. Providing accurate information is essential for patient safety and understanding.
2. A patient with an 18 pack per year history presents to a family practice clinic complaining of painless hoarseness and inability to clear mucus. A biopsy of respiratory tract cells is taken and shows that these cells have been replaced by less mature squamous epithelium cells. The nurse knows this type of change is referred to as:
- A. Dysplasia
- B. Metaplasia
- C. Hyperplasia
- D. Coagulation
Correct answer: B
Rationale: Metaplasia is the replacement of one type of cell with another, which can occur in response to chronic irritation, such as from smoking. In this case, the respiratory tract cells being replaced by less mature squamous epithelium cells indicate metaplasia. Dysplasia refers to abnormal development or growth of cells, not replacement; hyperplasia is an increase in the number of cells, not a replacement; and coagulation is a process related to blood clotting, not cell replacement.
3. During a home visit to a family of three: a mother, father, and their child, the mother tells the community nurse that the father (who is not present) had hit the child on several occasions when he was drinking. The mother further explains that she has talked her husband into going to Alcoholics Anonymous and asks the nurse not to interfere so her husband won’t get angry and refuse treatment. Which of the following is the best response of the nurse?
- A. The nurse agrees not to interfere if the husband attends an Alcoholics Anonymous meeting that evening.
- B. The nurse commends the mother’s efforts and agrees to let her handle things.
- C. The nurse commends the mother’s efforts and also contacts protective services.
- D. The nurse confronts the mother’s failure to protect the child.
Correct answer: C
Rationale: In this situation, the best response for the nurse is to commend the mother's efforts in seeking help for her husband by encouraging him to attend Alcoholics Anonymous. However, it is crucial for the nurse to also contact protective services to ensure the safety and well-being of the child. Option A is incorrect as it is not appropriate to condition non-interference on the husband attending a meeting that evening. Option B is incorrect because solely letting the mother handle things might put the child at risk. Option D is incorrect as it does not address the immediate need to ensure the child's safety through involving protective services.
4. When a child jumps out of the tub, crying and stating her feet are 'burning,' what pathophysiologic principle is responsible for this response?
- A. Pain receptors (nociceptors) have been activated in response to a thermal stimulus.
- B. The child's skin thermal receptors have undergone adaptation.
- C. The child is exhibiting a psychogenic pain response due to anxiety.
- D. The child is experiencing a conditioned pain response based on previous experiences.
Correct answer: A
Rationale: The child's reaction is due to the activation of nociceptors, which are pain receptors that respond to thermal stimuli. This response is an immediate protective mechanism to prevent tissue damage caused by extreme temperatures. Option B is incorrect because adaptation does not explain the child's immediate and intense response. Option C is incorrect as there is a clear physical stimulus present, ruling out a psychogenic response. Option D is incorrect as the child's response is not based on previous experiences but rather on the current thermal stimulus.
5. 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.
