In the care of patients with communicable diseases, Nurse Keena should know that feces, urine, blood and other body fluids are considered as ______.

Correct Answer: C

Rationale: Feces, urine, blood, and other body fluids are considered as vehicles of transmission in the context of communicable diseases. These substances can carry and transmit disease-causing microorganisms such as bacteria, viruses, and parasites from infected individuals to others. Through close contact or exposure to these contaminated body fluids, the pathogens can enter the body of another person and cause infection. Nurses like Nurse Keena must exercise caution and use appropriate infection control measures to prevent transmission of communicable diseases through these vehicles.

Correct Answer: A

Rationale: Administering a stool softener as ordered is the most appropriate nursing intervention for a postpartum client experiencing severe perineal pain and difficulty passing stools following a vaginal delivery. Stool softeners help to soften the stool, making it easier for the client to pass without straining, which can exacerbate perineal pain. It is important to follow the healthcare provider's orders when administering medications to ensure proper dosing and effectiveness. Encouraging the client to refrain from defecation may lead to constipation and worsen the situation. Applying ice packs to the perineum can provide temporary pain relief, but addressing the underlying issue of constipation with a stool softener is more effective in the long term. Providing education on proper perineal hygiene is important for overall postpartum care, but addressing the immediate issue of constipation with a stool softener takes precedence in this scenario.

Correct Answer: C

Rationale: In a postpartum client exhibiting signs of anxiety, restlessness, and palpitations, it is essential to prioritize notifying the healthcare provider immediately. These symptoms could indicate a serious condition such as postpartum preeclampsia, postpartum hemorrhage, or postpartum cardiomyopathy, which require urgent medical attention. It is crucial to rule out any life-threatening conditions and ensure the client receives appropriate treatment promptly. While relaxation techniques and deep breathing exercises can be helpful for anxiety management in some cases, in this situation, the priority is to ensure the client's safety and well-being by seeking medical evaluation and intervention. Administering a benzodiazepine without consulting the healthcare provider first could potentially mask symptoms or interact with other medications the client may be taking, making it unsafe to proceed without professional guidance.

Correct Answer: C

Rationale: In a pregnant patient with suspected pulmonary embolism (PE), the most appropriate imaging modality for evaluation is contrast-enhanced computed tomography (CT) pulmonary angiography. This imaging technique has been shown to be safe for the fetus when necessary, especially if the benefits of making a diagnosis outweigh the minimal risks associated with radiation exposure. It provides quick and accurate detection of PE with high sensitivity and specificity.

Correct Answer: D

Rationale: Option D demonstrates an effective communication technique used by the unit manager because it focuses on discussing strategic approaches to improve the delivery of nursing services while also considering cost effectiveness for the consumers. By emphasizing the need for strategic planning and efficient service delivery, the manager is promoting a proactive and solution-oriented approach rather than simply stating potential negative outcomes or making abrupt decisions like in the other options. This approach fosters more open communication, collaboration, and problem-solving within the team, ultimately leading to better outcomes and team morale.

Correct Answer: A

Rationale: At the concrete operational stage according to Piaget's theory, children typically demonstrate logical thinking abilities and are able to understand and work with concrete objects and events. They can also grasp concepts such as conservation and classification. These children are able to think logically about concrete events but may still struggle with abstract and hypothetical situations. Therefore, Belle, functioning at the concrete operational stage, would exhibit behaviors such as thinking logically and being able to see possibilities, as described in option A.

Correct Answer: D

Rationale: The large intestine, also known as the colon, is responsible for absorbing water and electrolytes from undigested food residue that passes through the digestive system after it has been processed in the small intestine. As the waste material moves through the colon, water is absorbed, and the remaining material forms feces. The feces are then stored until they are eliminated from the body through the rectum and anus. The liver, stomach, and pancreas play important roles in digestion and nutrient absorption, but the specific function of absorbing water and forming feces is carried out by the large intestine.

Correct Answer: C

Rationale: Mastitis is an infection of the breast tissue that may occur in postpartum clients. When a postpartum client exhibits signs of mastitis, including breast tenderness, erythema, and warmth, it is crucial to notify the healthcare provider immediately. Prompt medical evaluation is necessary to determine the appropriate treatment plan, which may include antibiotics. Delay in treatment can lead to complications, such as abscess formation. Encouraging the client to continue breastfeeding and applying warm compresses may provide some relief but do not address the underlying infection. Administering oral antibiotics would require a prescription from the healthcare provider, hence notifying the provider is the most appropriate initial nursing action in this situation.

Correct Answer: B

Rationale: Attending a lecture-demonstration on doing first aid is essential for the growth of a student nurse as it equips them with crucial knowledge and skills to respond effectively in emergency situations. First aid training teaches basic life-saving techniques and how to provide immediate care until medical professionals arrive. This knowledge is vital in the healthcare field, allowing the student nurse to provide immediate assistance and potentially save lives. By learning first aid procedures, the student nurse can enhance their skills, confidence, and overall capability to care for patients in various settings. This continuous learning and improvement are key to personal growth and professional development in the healthcare industry.
