Rh incompatibility can occur if the patient is Rh-negative and the
- A. fetus is Rh-negative.
- B. fetus is Rh-positive.
- C. father is Rh-positive.
- D. father and fetus are both Rh-negative.
Correct Answer: B
Rationale: The correct answer is B because Rh incompatibility occurs when an Rh-negative mother carries an Rh-positive fetus. If fetal blood enters the mother's circulation during pregnancy or childbirth, the mother's immune system can produce antibodies against Rh-positive red blood cells, leading to potential harm to future pregnancies. Choices A, C, and D are incorrect because Rh incompatibility does not occur when the fetus is Rh-negative, the father is Rh-positive, or both the father and fetus are Rh-negative.

A patient with a diagnosis of gastric cancer has been unable to tolerate oral food and fluid intake and her tumor location precludes the use of enteral feeding. What intervention should the nurse identify as best meeting this patients nutritional needs?
- A. Administration of parenteral feeds via a peripheral IV
- B. TPN administered via a peripherally inserted central catheter
- C. Insertion of an NG tube for administration of feeds
- D. Maintaining NPO status and IV hydration until treatment completion
Correct Answer: B
Rationale: The correct answer is B: TPN administered via a peripherally inserted central catheter. TPN provides comprehensive nutrition intravenously, bypassing the GI tract, which is important for patients unable to tolerate oral intake. A peripherally inserted central catheter allows for long-term TPN administration.
A: Administration of parenteral feeds via a peripheral IV is not ideal for long-term nutrition as it may not provide complete nutrition.
C: Insertion of an NG tube may not be feasible due to the tumor location and the patient's inability to tolerate oral intake.
D: Maintaining NPO status and IV hydration alone may lead to malnutrition over time as it does not provide adequate nutrition.
A patient is postoperative day 6 following tympanoplasty and mastoidectomy. The patient has phoned the surgical unit and states that she is experiencing occasional sharp, shooting pains in her affected ear. How should the nurse best interpret this patients complaint?
- A. These pains are an expected finding during the first few weeks of recovery.
- B. The patients complaints are suggestive of a postoperative infection.
- C. The patient may have experienced a spontaneous rupture of the tympanic membrane.
- D. The patients surgery may have been unsuccessful.
Correct Answer: A
Rationale: The correct answer is A. Postoperative day 6 following tympanoplasty and mastoidectomy is still within the early phase of recovery, where occasional sharp, shooting pains in the affected ear can be expected due to the healing process. Here's a step-by-step rationale:
1. Timing: It is only day 6 post-surgery, so it is normal to experience some pain as part of the healing process.
2. Nature of pain: Sharp, shooting pains are common post-surgery due to tissue healing and nerve regeneration.
3. Lack of other symptoms: The patient did not report any other concerning symptoms like fever or discharge, which would be more indicative of an infection.
4. Unlikely complications: Spontaneous rupture of the tympanic membrane or unsuccessful surgery would typically present with more severe and consistent symptoms.
Summary:
- B: Unlikely as there are no other signs of infection.
- C: Unlikely as the pain is described as occasional and sharp.
- D:
A patient has been diagnosed with hearing loss related to damage of the end organ for hearing or cranial nerve VIII. What term is used to describe this condition?
- A. Exostoses
- B. Otalgia
- C. Sensorineural hearing loss
- D. Presbycusis
Correct Answer: C
Rationale: The correct answer is C: Sensorineural hearing loss. This type of hearing loss is caused by damage to the inner ear or auditory nerve (cranial nerve VIII). Exostoses (A) are bony growths in the ear canal, not related to cranial nerve VIII. Otalgia (B) refers to ear pain, not hearing loss. Presbycusis (D) is age-related hearing loss, not specifically related to damage of the end organ for hearing or cranial nerve VIII. Therefore, C is the most appropriate term to describe the given condition.
The nurse is assessing a patient with multiple sclerosis who is demonstrating involuntary, rhythmic eye movements. What term will the nurse use when documenting these eye movements?
- A. Vertigo
- B. Tinnitus
- C. Nystagmus
- D. Astigmatism
Correct Answer: C
Rationale: The correct term for the involuntary, rhythmic eye movements seen in the patient with multiple sclerosis is nystagmus. Nystagmus is a condition characterized by repetitive, uncontrolled eye movements that can be horizontal, vertical, or rotary. In multiple sclerosis, nystagmus can occur due to damage to the nerves that control eye movement. Vertigo (choice A) is a sensation of spinning or dizziness, not related to eye movements. Tinnitus (choice B) is a perception of noise or ringing in the ears. Astigmatism (choice D) is a refractive error of the eye, not related to involuntary eye movements.
During a recent visit to the clinic a woman presents with erythema of the nipple and areola on the right breast. She states this started several weeks ago and she was fearful of what would be found. The nurse should promptly refer the patient to her primary care provider because the patients signs and symptoms are suggestive of what health problem?
- A. Peau dorange
- B. Nipple inversion
- C. Pagets disease
- D. Acute mastitis
Correct Answer: C
Rationale: Rationale:
1. Erythema of nipple/areola in one breast can be a sign of Paget's disease, a rare form of breast cancer.
2. Paget's disease may also present with itching, tingling, or a burning sensation in the affected area.
3. Referring the patient promptly is crucial for early detection and appropriate management.
4. Peau d'orange (A) is a sign of advanced breast cancer, not typically presenting with erythema alone.
5. Nipple inversion (B) may be benign or related to other conditions, not typically presenting with erythema.
6. Acute mastitis (D) presents with breast pain, warmth, swelling, and fever, but not typically with isolated erythema of the nipple/areola.
