A nurse is preparing to perform a chest tube insertion for a patient with a pneumothorax. What action should the nurse prioritize to ensure proper placement of the chest tube?

Correct Answer: D

Rationale: The correct answer is D because confirming the insertion site and direction using imaging guidance ensures precise placement of the chest tube, minimizing the risk of complications. Imaging guidance allows the nurse to visualize the exact location of the pneumothorax and guide the tube insertion accurately. A: Positioning the patient in a semi-Fowler's position with arms elevated may be beneficial for comfort but does not directly ensure proper chest tube placement. B: Marking the insertion site with a pen may help as a reference point but does not guarantee accurate placement. C: Administering analgesia is important for the patient's comfort but does not impact the placement of the chest tube. In summary, choice D is the most critical step to ensure the chest tube is correctly placed and effectively treats the pneumothorax.

Correct Answer: B

Rationale: The primary goal of CPR is to restore spontaneous circulation and oxygenation to the body to maintain vital organ function. By performing chest compressions and rescue breaths, CPR aims to circulate oxygenated blood to the brain and other vital organs. This is crucial to prevent brain damage and increase the chances of survival. The other choices are incorrect because CPR does not address the underlying cause of cardiac arrest (A), provide pain relief (C), or prevent further complications such as organ failure (D). The immediate focus in a cardiac arrest situation is to maintain blood flow and oxygen delivery to vital organs until advanced medical care can be provided.

Correct Answer: C

Rationale: The correct answer is C because independence for the elderly means they have the freedom to make choices and decisions about their own lives. This empowers them to live according to their preferences and values. Choice A is incorrect because it doesn't consider individual circumstances; choice B is important but doesn't capture the essence of independence; choice D is too broad and doesn't specifically address the concept of personal autonomy and agency for the elderly.

Correct Answer: D

Rationale: The correct answer is D because informed consent should be obtained from both the participants and their parents to ensure full understanding and agreement from all parties involved. This is crucial when working with minors to protect their rights and ensure ethical standards are met. Choice A is incorrect as it excludes parental consent, which is necessary for minors. Choice B is also incorrect as it neglects the participants' direct involvement in consenting to participate. Choice C is incorrect because it only includes available relatives, which may not be legally authorized to provide consent on behalf of the participants.

Correct Answer: B

Rationale: The correct answer is B: Psoriasis. Psoriasis is characterized by pruritic, erythematous patches with silvery scales, commonly found on the elbows, knees, and scalp. This presentation matches the patient's symptoms. Eczema (choice A) typically presents with red, inflamed, and itchy skin patches. Pityriasis rosea (choice C) manifests as a herald patch followed by smaller scaly patches in a "Christmas tree" distribution. Seborrheic dermatitis (choice D) involves oily, yellowish, scaly patches mainly on the scalp, face, and ears, and does not typically present with silvery scales.

Correct Answer: B

Rationale: The correct answer is B because actively listening, acknowledging the patient's concerns, and working towards rebuilding trust through transparency and reliability are essential steps in addressing distrust. By validating the patient's experiences and actively involving them in the process, the nurse can foster a supportive and trusting relationship. Choice A is incorrect because dismissing the patient's concerns can further damage trust and undermine the patient's feelings. Choice C is incorrect as ignoring the distrust can lead to a breakdown in communication and trust. Choice D is incorrect because telling the patient to trust the healthcare system without addressing their concerns is dismissive and unhelpful.

Correct Answer: C

Rationale: The correct answer is C: Fifth month. Nurse Vera should explain that the fetal heart can typically be heard using a Doppler ultrasound device around the fifth month of pregnancy. This is because the baby's heart is developed enough to produce audible sounds by this time. Choices A, B, and D are incorrect because in the ninth month, the baby is ready for delivery, in the third month the heart is still developing, and in the first month the heart is just beginning to form and is not yet audible.

Correct Answer: B

Rationale: The correct answer is B: Equity in services. Collaboration and teamwork in public health are crucial to ensure equal access to services for all populations, regardless of their background or socioeconomic status. By working together, public health professionals can identify disparities and implement strategies to address them, ultimately leading to improved equity in healthcare services. A: Staff performance - While collaboration and teamwork can positively impact staff performance, the primary focus in public health is on achieving equity in services for all individuals. C: Proper use of resources - Collaboration can help optimize resource allocation, but the main goal in public health is to ensure equitable access to services. D: Quality healthcare - While collaboration can enhance the quality of healthcare, the primary emphasis in public health is on promoting equity in services to address health disparities.

Correct Answer: C

Rationale: In a postpartum client complaining of persistent, heavy vaginal bleeding, the most appropriate nursing action is to assess vital signs and uterine tone. This is important to determine if the bleeding is within normal limits or if there is a potential postpartum hemorrhage (PPH) occurring. Monitoring vital signs can help identify signs of shock, while assessing uterine tone can help determine if the uterus is contracting effectively to control bleeding. Prompt assessment and early detection of PPH are crucial for effective management and prevention of complications. Encouraging increased fluid intake, applying a cold compress, and administering pain medication may be appropriate interventions in some situations, but assessing vital signs and uterine tone take priority in this scenario.
