Correct Answer: C

Rationale: The correct response would be "Absorption of iron is enhanced with Vitamin C." Iron absorption is increased in the presence of Vitamin C. Therefore, recommending Evelyn to take her iron supplement with a source of Vitamin C such as orange juice or a Vitamin C tablet would optimize the absorption of iron in her body and help prevent maternal anemia more effectively. Taking iron with other vitamins separately, after a full meal, or with milk would not have the same beneficial effect on iron absorption as combining it with Vitamin C.

Correct Answer: D

Rationale: Prinzmetal's angina, also known as variant angina, is characterized by episodes of chest pain that occur at rest and are relieved by nitroglycerin. Patients with Prinzmetal's angina may also have transient ST-segment elevation on an electrocardiogram (ECG) during episodes of chest pain. This is due to coronary artery vasospasm, which causes temporary obstruction of blood flow to the heart muscle. Stable angina typically presents with chest pain on exertion that resolves with rest, while unstable angina and acute myocardial infarction present with chest pain that is not relieved with nitroglycerin and are associated with more severe coronary artery disease.

Correct Answer: B

Rationale: Nursing interventions should be aimed at addressing the mother's needs for psychological security. Hyper vigilance and excessive worry about her child's safety indicate a lack of security in her mind. By providing support, reassurance, and education, nurses can help the mother feel more secure in her role as a parent and reduce her feelings of anxiety and distress. Establishing trust and building a therapeutic relationship can also contribute to enhancing the mother's psychological security and well-being.

Correct Answer: D

Rationale: Record keeping involves several key steps such as structuring, securing, and storing information. However, easy disposal is not a step in record keeping. In fact, it is important to carefully consider the disposal of records in a secure and responsible manner to protect sensitive information and comply with relevant regulations. Proper disposal methods should be followed to ensure that records are not accessible to unauthorized individuals and that any sensitive information is properly destroyed to prevent misuse or breaches of privacy. Therefore, easy disposal is not a recommended practice in effective record keeping.

Correct Answer: C

Rationale: The nurse does not need to determine the age of Excel when planning for Sonny's oxygen therapy. This information is irrelevant to the specific care requirements of Sonny's oxygen therapy. Sonny's age, medical history, respiratory status, and oxygen needs are the key considerations in planning for his oxygen therapy. The nurse should focus on factors such as the need for a humidifier, length of tubing, and the manner of administering oxygen (continuous or intermittent) to ensure effective and safe delivery of oxygen therapy to Sonny.
