A patient with a history of heart failure is prescribed a beta-blocker. Which assessment finding indicates a therapeutic effect of beta-blocker therapy?

Correct Answer: A

Rationale: Beta-blockers are medications commonly used in the management of heart failure. One of the therapeutic effects of beta-blockers is to decrease the heart rate. By blocking the action of adrenaline on the heart, beta-blockers help to slow down the heart rate, reduce the workload on the heart, and improve overall heart function. In patients with heart failure, a decreased heart rate is a favorable outcome as it can help improve cardiac output and reduce symptoms of heart failure such as fatigue and shortness of breath. Monitoring the heart rate is an important assessment parameter to evaluate the effectiveness of beta-blocker therapy in patients with heart failure. Therefore, a decreased heart rate would indicate a therapeutic effect of beta-blocker therapy in this patient.

Correct Answer: A

Rationale: When handling information about families in the community, the nurse should consider the principle of confidentiality as ethical. Confidentiality refers to the obligation of healthcare providers to safeguard the privacy of patient information. By maintaining confidentiality, the nurse upholds trust and respect in the nurse-family relationship. This principle ensures that sensitive information shared by families is kept secure and not disclosed without permission, thus respecting their autonomy and promoting open communication in healthcare settings.

Correct Answer: A

Rationale: The right to considerate and respectful care irrespective of socio-economic status is applicable in this case because Mr. Steve is facing financial difficulties in paying for his medical bills. This right ensures that all patients receive proper treatment and care regardless of their ability to pay. It emphasizes that every individual deserves to be treated with dignity and respect, regardless of their financial situation. In Mr. Steve's case, being referred to a social worker due to inability to pay should not impact the quality of care and respect he receives from healthcare providers.

Correct Answer: A

Rationale: The presentation of sudden-onset, painless vision loss in the right eye with a cherry-red spot at the macula and attenuated retinal vessels is classic for central retinal artery occlusion (CRAO). In this condition, the blockage of the central retinal artery results in severe ischemia of the retina, leading to rapid and profound vision loss. The cherry-red spot at the macula is a result of preserved choroidal circulation contrasting with the pale, ischemic retina. Attenuated retinal vessels are also commonly observed due to decreased blood flow. Prompt evaluation and management are critical in CRAO to potentially restore some vision and prevent further ischemic damage to the retina.

Correct Answer: A

Rationale: The most appropriate nursing intervention to alleviate breast engorgement and discomfort in a breastfeeding client is to encourage frequent breastfeeding or pumping sessions. Engorgement occurs when the breasts become overly full of milk, causing them to become swollen, firm, and painful. By ensuring that the baby breastfeeds frequently, the client can effectively empty the breasts, which helps to relieve engorgement and discomfort. Encouraging the client to breastfeed on demand and ensuring proper latching can help prevent further engorgement issues. Pumping can also be useful if the baby is unable to feed directly from the breast or to relieve engorgement between feedings. This intervention addresses the root cause of the problem and promotes the client's comfort and breastfeeding success. Applying cold packs, using a supportive bra or breast binder, and administering oral analgesics may provide some relief for discomfort but do not address the underlying issue of engorgement.

Correct Answer: C

Rationale: The indicators listed indicate measures that Nurse Cirila can take to maintain a safe environment for her pediatric patients. However, assessing the competencies of staff before delegating a task is more related to ensuring effective delegation and appropriate task assignment rather than directly ensuring a safe environment for patients. While it is important to delegate tasks to qualified staff, this specific action does not directly contribute to maintaining a safe environment in the same manner as the other indicators listed (proper waste disposal, infection control, emergency protocols).

Correct Answer: D

Rationale: A delimitation in a research study refers to setting specific boundaries or restrictions on the scope of the study. In this scenario, Gloria's decision to include only nurses with a minimum of three years experience as psychiatric nurses is a delimitation because it sets a specific criterion or boundary for the selection of participants. This helps to focus the study on a particular group of individuals who possess the required experience, ensuring the research is targeted and relevant to the topic being investigated.

Correct Answer: C

Rationale: The correct response for the nurse in this situation would be to offer the victim a shower after evidence is collected. It is essential to preserve any physical evidence that may be present from the assault during the forensic examination. Allowing the victim to shower before evidence is collected could potentially compromise the evidence and hinder the investigation. The nurse should provide support to the victim during this difficult time and assure them that they will have the opportunity to shower once the necessary evidence is obtained. It is also crucial for the nurse to offer empathy and understanding while explaining the importance of preserving any evidence related to the assault.

Correct Answer: C

Rationale: In this situation, it is crucial for the nurse to inform the surgeon immediately and request corrective action. Maintaining a sterile field during surgical procedures is essential to prevent infections and ensure patient safety. Any break in sterile technique should be addressed promptly to prevent any potential harm to the patient. By informing the surgeon immediately, corrective action can be taken promptly to maintain the sterility of the surgical field and minimize the risk of complications. Reporting the incident to the surgeon also allows for immediate intervention and re-education of the team member involved in the break in sterile technique.
