The primary critical observation for Apgar scoring is the:
- A. Heart rate
- B. Respiratory rate
- C. Presence of meconium
- D. Evaluation of the Moro reflex
Correct Answer: A
Rationale: The primary critical observation for Apgar scoring is the heart rate. This is because the heart rate is vital for life and immediate assessment of the infant's heart rate provides crucial information about the baby's overall well-being and response to the birthing process. The Apgar score assesses five components: heart rate, respiratory effort, muscle tone, reflex irritability, and skin color. Among these components, the heart rate is considered the most critical because it directly reflects the infant's cardiovascular status and their ability to maintain adequate perfusion of vital organs. Therefore, for quick assessment and immediate intervention, the heart rate is prioritized as the primary observation in Apgar scoring.
Which blood gas analyses are most indicative of respiratory acidosis?
- A. pH = 7.22, PCO2 = 55 mmHg, HCO3 = 30 mEq/L.
- B. pH = 7.28, PCO2 = 45 mmHg, HCO3 = 15 mEq/L.
- C. pH = 7.34, PCO2 = 35 mmHg, HCO3 = 25 mEq/L.
- D. pH = 7.40, PCO2 = 25 mmHg, HCO3 = 30 mEq/L.
Correct Answer: A
Rationale: Respiratory acidosis is indicated by a low pH and elevated PCO2, as seen in option A.
The nurse is assigned to care for a postoperative client who has diabetes mellitus. During the assessment interview, the client reports that he's impotent and says he's concerned about its effect on his marriage. In planning this client's care, the most appropriate intervention would be to:
- A. Encourage the client to ask questions about personality sexuality
- B. Provide time for privacy
- C. Provide support for the spouse or significant other
- D. Suggest referral to a sex counselor or other appropriate professional
Correct Answer: D
Rationale: Suggesting a referral to a sex counselor or other appropriate professional would be the most appropriate intervention in this case. Impotence or erectile dysfunction can have significant emotional and psychological implications, especially in the context of a marital relationship. A sex counselor or therapist who specializes in sexual health can provide the necessary support, guidance, and strategies to help the client and his spouse navigate this issue effectively. This intervention is aimed at addressing the client's concerns about impotence, its impact on his marriage, and ultimately promoting holistic well-being.
You are assigned to evaluate the outcome of fecal occult blood test as a screening test for patients with bowel cancer. The total number of patients who underwent the test is 2030; in those whom the disease is confirmed are 30. The results of fecal occult blood test are as follows: in 20 patients who has a confirmed bowel cancer (truly positive), and in 180 patients who don't have the disease (falsely positive); in 10 patients who truly has the disease (falsely negative), and in 1820 patients who are not affected by the disease (truly negative). All the following statements are true EXCEPT
- A. the prevalence of the disease for those population is 1.48%
- B. the sensitivity of the test is 67%
- C. the specificity of the test is 91%
- D. the positive predictive value is 20%
Correct Answer: A
Rationale: Prevalence = (Total cases / Total population) * 100 = (30 / 2030) * 100 ≈ 1.48%. This statement is correct, so it is the exception as the question asks for the incorrect statement.
Where do the lesions of atopic dermatitis (eczema) most commonly occur in the infant? (Select all that apply.)
- A. Cheeks
- B. Buttocks
- C. Extensor surfaces of arms and legs
- D. Back
Correct Answer: A
Rationale: In infants with atopic dermatitis (eczema), the lesions most commonly occur on the cheeks (option A) and the extensor surfaces of the arms and legs (option C). The cheeks are a common site of involvement due to increased exposure to irritants and saliva from drooling. The extensor surfaces of the arms and legs are also frequently affected due to scratching and rubbing against clothing. While atopic dermatitis can occur in other areas such as the buttocks, back, and trunk, the cheeks and extensor surfaces are the most common locations in infants.
