The first standard step in oxygen therapy that the nurse should do is________.

Correct Answer: A

Rationale: The first standard step in oxygen therapy that the nurse should do is to assess the client's condition. Before initiating any oxygen treatment, it is essential to assess the client's respiratory status, oxygen saturation levels, vital signs, and overall condition. This initial assessment helps the nurse to determine the appropriate course of oxygen therapy based on the client's individual needs and current health status. Assessing the client's condition first ensures that the oxygen therapy provided is safe and effective for the specific needs of the client.

Correct Answer: A

Rationale: In prioritizing nursing diagnoses, the nurse should consider issues that pose the greatest risk to the patient's immediate well-being. A fluid volume deficit can lead to dehydration and potentially life-threatening complications, making it a priority to address. It is crucial to restore fluid balance to maintain normal body functions and prevent further deterioration of the patient's condition. Ensuring adequate hydration is essential for the patient's overall health and recovery. The other options, such as risk for pain, coping, and body image disturbances, while important, are not as urgent as addressing a fluid volume deficit.

Correct Answer: C

Rationale: The hypothalamus is the link between the nervous system and the endocrine system. It plays a crucial role in maintaining homeostasis in the body by communicating with the pituitary gland, which is often referred to as the "master gland" of the endocrine system. The hypothalamus produces hormones that regulate the release of hormones from the pituitary gland, which then controls the functions of other endocrine glands throughout the body. This connection allows the nervous system to influence and coordinate various hormonal responses in the body, helping to regulate processes such as metabolism, growth, stress responses, and reproduction.

Correct Answer: C

Rationale: Normal saline solution is the best choice for cleaning Claudia's eyes with drainage. It is a sterile solution that closely matches the natural pH of the eyes, making it gentle and safe for ocular use. Normal saline can help flush out any debris or discharge in the eye without causing further irritation or complications. On the other hand, hydrochloric acid is a corrosive substance that can cause significant harm if it comes into contact with the eyes. Mineral water may contain impurities that could further irritate the eyes. Soapsuds solution is not recommended for eye cleaning as it can cause irritation and damage to the delicate eye tissues. Therefore, normal saline solution is the most appropriate and safe option for cleaning Claudia's eyes in this situation.

Correct Answer: C

Rationale: Total Parenteral Nutrition (TPN) is a method of providing nutrition to patients who cannot or should not obtain their nutrition through regular oral intake. The primary goals of TPN include promoting weight gain, improving nutritional status, maintaining muscle mass, and establishing nitrogen balance. These goals are crucial to support the overall health and well-being of the patient receiving TPN. Enhancing the healing process is an important aspect of TPN as well, but it is not considered one of the primary goals as weight gain, nutritional status, muscle mass, and nitrogen balance are typically the immediate priorities when administering TPN.
