The nurse is caring for a client with acquired immunodeficiency syndrome (AIDS). To adhere to standard precautions, the nurse should:

Correct Answer: B

Rationale: The correct answer is B: Wear gloves when providing mouth care. This is because standard precautions for AIDS include wearing gloves when in contact with bodily fluids, such as saliva during mouth care. Maintaining strict isolation (A) is not necessary as AIDS is not transmitted through casual contact. Keeping the client in a private room (C) is not required unless the client has an airborne infection. Wearing a gown when delivering food tray (D) is not necessary for standard precautions unless there is a risk of contamination with bodily fluids.

Correct Answer: D

Rationale: Step 1: Monitoring electrolytes is essential to assess for potential imbalances due to the use of sodium bicarbonate, which can lead to hypokalemia and hypocalcemia. Step 2: Hypokalemia and hypocalcemia can result in serious complications such as cardiac arrhythmias and muscle weakness. Step 3: By monitoring electrolytes, the nurse can detect imbalances early and intervene promptly to prevent adverse effects. Summary: A: Drinking excessive water can lead to electrolyte imbalances and is not directly related to the use of sodium bicarbonate. B: Administering NaHCO3 IV is not within the nurse's scope of practice and should be done based on physician's orders. C: Continuing sodium bicarbonate for nausea may not be appropriate without monitoring electrolytes to prevent potential imbalances.

Correct Answer: A

Rationale: The correct answer is A: Medulla. The medulla is located in the brainstem and plays a crucial role in controlling involuntary functions like breathing. It contains the respiratory center, which regulates the rate and depth of breathing. The medulla sends signals to the diaphragm and intercostal muscles to control breathing. The cerebrum (B) is responsible for higher brain functions, not breathing control. The cerebellum (C) coordinates movement and balance, not breathing. The thalamus (D) relays sensory information to the cerebral cortex, not involved in breathing regulation.

Correct Answer: B

Rationale: The correct answer is B. Placing the patient on the right side with support to the back, pillows for body alignment, hips slightly flexed, and a washcloth placed so that fingers are slightly curled is most appropriate for a patient with right-sided paralysis following a stroke. This position helps prevent contractures by maintaining proper alignment and positioning of the limbs. Placing the washcloth to curl the fingers helps prevent hand contractures. Supporting the back and keeping the hips slightly flexed also helps prevent pressure ulcers and maintains proper body alignment. Choice A is incorrect because tightly holding a rolled washcloth may cause discomfort and restrict blood flow. Choice C is incorrect because placing the patient on the back with a pillow under the knees does not address the specific needs of a patient with right-sided paralysis. Choice D is incorrect because lying on the back with trochanter rolls and a footboard does not address the specific needs of a patient with right-sided paralysis and may not prevent contractures effectively.

Correct Answer: C

Rationale: The correct answer is C, bilateral crackles. Fluid in both lung bases on x-ray indicates pulmonary edema, causing crackles on auscultation. Fatigue (A) is a nonspecific symptom. Peripheral edema (B) is a sign of fluid retention in the extremities, not lungs. Jugular vein distention (D) indicates increased central venous pressure, which is not specific to lung fluid.

Correct Answer: C

Rationale: The correct answer is C (600ml/24hr) because insensible fluid losses in an afebrile person are typically around 600ml per 24 hours. Insensible losses include water lost through the skin as sweat and through the lungs during respiration. These losses are not easily quantifiable but are estimated to be around 600ml/day in normal circumstances. Choices A, B, and D are incorrect because they are either too low (A and B) or too high (D) compared to the normal range of insensible fluid losses. Selecting C as the correct answer is based on the understanding of physiological principles related to fluid balance and normal body functions.

Correct Answer: C

Rationale: Rationale: 1. Safety: Recording vital signs is crucial for patient safety. 2. Accountability: The nurse is ultimately responsible for ensuring vital signs are documented accurately. 3. Communication: It is essential for the nurse to communicate with the NAP to address the missed vital signs. 4. Corrective Action: Asking the NAP to record vital signs before administering medications ensures proper monitoring. 5. Patient-Centered Care: Prioritizing patient well-being by ensuring vital signs are up-to-date. Summary: A: Incorrect. Administering medications without vital sign assessment is unsafe. B: Incorrect. Reviewing vital signs upon return does not address the immediate need for accurate documentation. D: Incorrect. Omitting vital signs compromises patient safety and violates standard nursing practice.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): Asking the NAP to record the patient's vital signs before administering medications is the correct clinical decision. Vital signs are crucial indicators of a patient's health status and should be documented before any interventions. By having the NAP record the vital signs, the nurse ensures that the patient's condition is properly assessed and monitored. This action aligns with the standard of care and promotes patient safety. Summary of Incorrect Choices: A: Administering medications without knowing the patient's vital signs could be dangerous, especially if there are abnormalities that need attention. B: Reviewing vital signs upon return delays necessary assessment and intervention, potentially compromising patient safety. D: Omitting vital signs without assessment puts the patient at risk, as changes in vital signs can indicate underlying issues that need immediate attention.

Correct Answer: C

Rationale: The correct answer is C: Alteration in tissue perfusion related to bleeding and diminished blood flow. Disseminated intravascular coagulation (DIC) is a condition where blood clots form throughout the body, leading to both bleeding and clotting. This can result in decreased blood flow to tissues, causing tissue perfusion issues. Explanation: 1. Option A: Risk for increased cardiac output related to fluid volume excess is incorrect because DIC can lead to bleeding, causing a decrease in blood volume and potentially decreasing cardiac output. 2. Option B: Disturbed sensory perception related to bleeding into tissues is incorrect as DIC primarily affects blood clotting and bleeding, not sensory perception. 3. Option D: Risk for aspiration related to constriction of the respiratory musculature is incorrect as DIC does not directly cause constriction of respiratory muscles, but rather impacts the clotting and bleeding processes in the body. In summary, the correct answer is C because DIC can lead to altered tissue perfusion
