A patients decline in respiratory and renal function has been attributed to Goodpasture syndrome, which is a type II hypersensitivity reaction. What pathologic process underlies the patients health problem?
- A. Antigens have bound to antibodies and formed inappropriate immune complexes.
- B. The patients body has mistakenly identified a normal constituent of the body as foreign.
- C. Sensitized T cells have caused cell and tissue damage.
- D. Mast cells have released histamines that directly cause cell lysis.
Correct Answer: B
Rationale: The correct answer is B because in Goodpasture syndrome, the patient's immune system mistakenly targets normal constituents of the body, specifically the basement membrane of the kidneys and lungs. This autoimmune response leads to inflammation and damage in these organs, resulting in respiratory and renal dysfunction.
Choice A is incorrect as immune complexes are not the primary mechanism in Goodpasture syndrome. Choice C is incorrect as it refers to T cell-mediated immune responses, which are not the main drivers in this condition. Choice D is incorrect as histamine release and cell lysis are not the main processes involved in Goodpasture syndrome.

Nursing intervention for pregnant patients with diabetes is based on the knowledge that the need for insulin is
- A. varied depending on the stage of gestation.
- B. increased throughout pregnancy and the postpartum period.
- C. decreased throughout pregnancy and the postpartum period.
- D. should not change because the fetus produces its own insulin.
Correct Answer: A
Rationale: Rationale:
1. Insulin needs change during pregnancy due to hormonal changes.
2. During the first trimester, insulin needs may decrease.
3. During the second and third trimesters, insulin needs increase.
4. Postpartum, insulin needs return to pre-pregnancy levels.
Therefore, choice A is correct as insulin needs vary based on gestational stage. Choices B, C, and D are incorrect because insulin needs do not uniformly increase or decrease throughout pregnancy or due to fetal insulin production.
A patient with mastoiditis is admitted to the post-surgical unit after undergoing a radical mastoidectomy. The nurse should identify what priority of postoperative care?
- A. Assessing for mouth droop and decreased lateral eye gaze
- B. Assessing for increased middle ear pressure and perforated ear drum
- C. Assessing for gradual onset of conductive hearing loss and nystagmus
- D. Assessing for scar tissue and cerumen obstructing the auditory canal
Correct Answer: A
Rationale: The correct answer is A: Assessing for mouth droop and decreased lateral eye gaze. After a radical mastoidectomy, the nurse should prioritize assessing for signs of facial nerve damage, such as mouth droop and decreased lateral eye gaze, which can indicate injury to the facial nerve during surgery. This is crucial as immediate intervention may be needed to prevent long-term complications.
Choices B, C, and D are incorrect:
B: Assessing for increased middle ear pressure and perforated ear drum is not the priority postoperative care for a radical mastoidectomy patient.
C: Assessing for gradual onset of conductive hearing loss and nystagmus is not the priority as these are not immediate concerns postoperatively.
D: Assessing for scar tissue and cerumen obstructing the auditory canal is not the priority as these are not immediate postoperative complications that require urgent attention.
A patient, diagnosed with cancer of the lung, has just been told he has metastases to the brain. What change in health status would the nurse attribute to the patients metastatic brain disease?
- A. Chronic pain
- B. Respiratory distress
- C. Fixed pupils
- D. Personality changes
Correct Answer: D
Rationale: The correct answer is D: Personality changes. Metastases to the brain can affect cognitive function and behavior, leading to personality changes. This is due to the impact on specific areas of the brain responsible for personality and behavior. Chronic pain (A) is more commonly associated with advanced cancer and not specific to brain metastases. Respiratory distress (B) is more likely related to lung cancer itself, not brain metastases. Fixed pupils (C) may indicate brainstem involvement, but personality changes are a more direct and common manifestation of brain metastases.
A patient on the medical unit is dying and the nurse has determined that the familys psychosocial needs during the dying process need to be addressed. What is a cause of many patient care dilemmas at the end of life?
- A. Poor communication between the family and the care team
- B. Denial of imminent death on the part of the family or the patient
- C. Limited visitation opportunities for friends and family
- D. Conflict between family members
Correct Answer: B
Rationale: The correct answer is B: Denial of imminent death on the part of the family or the patient. This is a common cause of patient care dilemmas at the end of life because denial can lead to unrealistic expectations, difficulty in making important decisions, and inadequate planning for end-of-life care. This can result in unnecessary suffering for the patient and added stress for the family.
Incorrect choices:
A: Poor communication between the family and the care team can contribute to challenges in providing appropriate care but may not be the primary cause of patient care dilemmas at the end of life.
C: Limited visitation opportunities for friends and family, while important for psychosocial support, may not directly cause patient care dilemmas.
D: Conflict between family members can complicate decision-making processes, but it is not necessarily a primary cause of patient care dilemmas at the end of life.
The nurse in an extended care facility is planning the daily activities of a patient with postpolio syndrome. The nurse recognizes the patient will best benefit from physical therapy when it is scheduled at what time?
- A. Immediately after meals
- B. In the morning
- C. Before bedtime
- D. In the early evening
Correct Answer: B
Rationale: The correct answer is B: In the morning. This is because scheduling physical therapy in the morning allows the patient to benefit from increased energy levels and improved muscle strength and function after a night of rest. Morning sessions can also help set a positive tone for the rest of the day.
Choice A: Immediately after meals can lead to discomfort and potential complications like indigestion or reflux.
Choice C: Before bedtime may be too late in the day when fatigue levels are higher and may disrupt sleep patterns.
Choice D: In the early evening may be less effective as fatigue accumulates throughout the day, and the patient may not have the same level of energy and focus as in the morning.
