The mother of a 3-month-old infant states that her baby has not been gaining weight. With further questioning, the nurse finds that the infant falls asleep after nursing and wakes up after a short time, hungry again. What other information would the nurse want to have?

Correct Answer: D

Rationale: The correct answer is D: Presence of dyspnea or diaphoresis when sucking. This information is crucial as it could indicate a medical issue such as a respiratory problem or heart condition affecting the baby's ability to feed properly, leading to poor weight gain. Dyspnea (difficulty breathing) and diaphoresis (excessive sweating) during sucking are red flags that require immediate medical attention. A: The infant's sleeping position is important for preventing Sudden Infant Death Syndrome (SIDS) but not directly related to the feeding issue. B: Sibling history of eating disorders may not be relevant to the current infant's feeding difficulties. C: Amount of background noise when eating is unlikely to be the primary factor affecting the infant's weight gain issue.

Correct Answer: A

Rationale: The correct answer is A. Intraluminal valves ensure unidirectional flow toward the heart. These valves prevent backflow and promote blood flow towards the heart. Skeletal muscle contractions (choice B) help propel blood towards the heart, but they do not ensure unidirectional flow. The heart is not a high-pressure system (choice C), and venous return relies more on mechanisms outside the heart. Choice D incorrectly suggests that thoracic and abdominal pressure changes facilitate venous return, but the primary mechanism is the presence of one-way valves in veins.

Correct Answer: A

Rationale: The correct answer is A. Nonpitting, hard edema is commonly associated with lymphatic obstruction. Lymphatic obstruction prevents the drainage of interstitial fluid, leading to accumulation and the characteristic nonpitting, hard edema. In this case, the presence of edema in only the left lower leg and ankle suggests localized lymphatic obstruction. Choice B is incorrect because alterations in arterial function typically result in arterial insufficiency and not edema. Choice C is incorrect because phlebitis of a superficial vein usually causes unilateral edema rather than bilateral edema. Choice D is incorrect as long-standing arterial obstruction typically leads to tissue ischemia rather than pitting edema.

Correct Answer: C

Rationale: The correct answer is C: Silent patient. Mrs. R.'s lack of response to the question despite being asked directly indicates she is a silent patient. This type of patient may be non-communicative due to various reasons such as anxiety, cognitive impairment, or being passive in decision-making. In this case, Mrs. R. may be relying on her daughter to communicate for her. The other choices are incorrect because Mrs. R. is not talkative, angry, or necessarily hearing-impaired based on the information provided. It is important for healthcare providers to recognize and adapt their communication strategies to effectively engage with silent patients.

Correct Answer: B

Rationale: Correct Answer: B (Consider admitting the patient to the hospital) Rationale: 1. Dakota is a 14-year-old boy with a sudden rash, slight fever, and no known exposure. 2. The rash is non-blanching which indicates a serious underlying condition like meningococcal infection. 3. Meningococcal infection can progress rapidly, leading to life-threatening complications. 4. Hospital admission allows for close monitoring, diagnostic tests, and prompt treatment if needed. Summary of other choices: A: Steroid cream is not appropriate as the rash could be a sign of a serious infection, not just inflammation. C: Relying on reassurance without proper evaluation can delay necessary treatment. D: Following up in 3 days may be too late if the condition worsens rapidly.
