Correct Answer: B

Rationale: Observing a 1-month-old tiring out during feedings should alert the nurse to the possibility of a congenital heart defect. This symptom may indicate that the infant is expending excess energy to compensate for a heart issue, leading to fatigue during feeding. Choices A, C, and D do not directly relate to a congenital heart defect. Being always hungry, fussy, or sleeping a lot are not specific signs of a congenital heart defect in a 1-month-old.

Correct Answer: D

Rationale: Enteric fever, caused by Salmonella typhi or paratyphi, is characterized by a continuous fever pattern. The fever typically persists without significant fluctuations, distinguishing it from diseases with intermittent or relapsing fever patterns. Pel-Ebstein fever, a cyclic pattern of fever seen in Hodgkin's lymphoma, is not associated with enteric fever. Relapsing fever is a characteristic of diseases like Borrelia recurrentis infection. Intermittent fever is seen in conditions like malaria.

Correct Answer: B

Rationale: Evaluation is the correct stage in the nursing process to determine if the patient has achieved the expected outcomes. During the evaluation stage, the healthcare provider assesses the effectiveness of the care plan and decides on any necessary adjustments to reach the desired goals. Choice A, Implementation, is incorrect because this stage involves putting the care plan into action. Choice C, Assessment, is incorrect as it is the stage where data about the patient's health status is gathered. Choice D, Diagnosis, is also incorrect as it is the stage where the healthcare provider identifies the patient's health problems based on the assessment data.

Correct Answer: C

Rationale: Aortic stenosis is a condition characterized by the narrowing of the aortic valve, leading to reduced blood flow from the heart to the body. This narrowing restricts the amount of oxygenated blood that can reach various tissues, including muscles. As a result, individuals with aortic stenosis may experience exercise intolerance, as their muscles may not receive an adequate oxygen supply during physical activity. This can manifest as fatigue, shortness of breath, and overall decreased exercise capacity. Pallor (choice A) is a pale appearance that may be seen in anemia or other conditions affecting blood flow but is not specific to aortic stenosis. Hyperactivity (choice B) and gastrointestinal disturbances (choice D) are not typically associated with aortic stenosis.

Correct Answer: A

Rationale: Hypopituitarism is characterized by linear growth retardation with skeletal proportions normal for chronologic age. This means that although the child experiences growth retardation, their skeletal proportions are appropriate for their age, which distinguishes it from other conditions like precocious puberty or equal height and weight affectation. Choice B is incorrect as hypopituitarism does not involve precocious puberty. Choice C is wrong as it describes a different growth pattern not typical of hypopituitarism. Choice D is also incorrect as in hypopituitarism, height and weight are not equally affected, rather the focus is on linear growth retardation with normal skeletal proportions.
