The nurse working in the emergency department (ED) is assessing an infant client. Which findings does the nurse anticipate in a child diagnosed with respiratory syncytial virus (RSV)? Select one that doesn't apply.

Correct Answer: D

Rationale: Rationale: The correct answer is D) Bradypnea. Respiratory syncytial virus (RSV) is a common respiratory virus that can cause mild to severe respiratory symptoms, especially in infants and young children. Bradypnea, which refers to abnormally slow breathing, is not typically associated with RSV. Instead, children with RSV commonly present with symptoms such as rhinorrhea (runny nose), irritability, and grunting. Rhinorrhea is a common symptom of RSV as the virus primarily affects the respiratory system leading to nasal congestion and discharge. Irritability is often seen in infants with respiratory distress due to the discomfort and difficulty in breathing. Grunting is a sign of increased work of breathing and is a common finding in infants with respiratory distress, including those with RSV. In an educational context, understanding the typical symptoms and clinical manifestations of RSV is crucial for healthcare providers, especially nurses working in settings like the emergency department where they may encounter pediatric patients with respiratory infections. Recognizing these symptoms early can lead to timely interventions and appropriate management to improve patient outcomes. By knowing what to expect in a child with RSV, nurses can provide efficient and effective care, including appropriate oxygen therapy if needed.

Correct Answer: A

Rationale: In this question, the correct answer is A) No life would exist on earth. This is because if all the oxygen present in the environment were converted to ozone, there would be a severe depletion of oxygen levels in the atmosphere, making it impossible for most forms of life to survive. Ozone (O3) is a molecule composed of three oxygen atoms, whereas the oxygen we breathe is O2, consisting of two oxygen atoms. Ozone is essential in the upper atmosphere as it protects us from harmful ultraviolet radiation, but at ground level, it is a pollutant and can be harmful to living organisms. Option B) Life would improve is incorrect because the conversion of all oxygen to ozone would have detrimental effects on life on Earth. Option C) Plants would thrive is also incorrect because, like other living organisms, plants require oxygen for respiration, and a lack of oxygen would lead to their demise as well. From an educational perspective, this question highlights the critical role that oxygen plays in supporting life on Earth and the potential consequences of a significant change in its composition. It underscores the importance of understanding basic chemistry concepts and the delicate balance of gases in our atmosphere for the sustenance of life.

Correct Answer: C

Rationale: In this question, the correct answer is C) Right kidney lower, Right lung shorter. The presence of the liver on the right side of the body causes the right kidney to be positioned lower than the left kidney and the right lung to be shorter than the left lung. To elaborate, the liver is a large organ located predominantly on the right side of the abdominal cavity. It occupies space that would otherwise be taken up by the right kidney and right lung. This anatomical relationship results in the right kidney being positioned lower than the left kidney and the right lung being shorter than the left lung. Option A) Left kidney slightly lower, Left lung slightly shorter is incorrect because it does not account for the impact of the liver on the right side of the body. Option B) Left kidney slightly higher, Left lung slightly shorter is incorrect as it inaccurately describes the positioning of the kidneys and lungs relative to each other. Option D) Right kidney higher, Right lung shorter is incorrect because the presence of the liver causes the right kidney to be lower, not higher. Understanding these anatomical differences is crucial in medical education, especially in disciplines like anatomy, physiology, and respiratory therapy. It is essential for healthcare professionals to have a solid grasp of the spatial relationships between organs to accurately interpret diagnostic imaging, perform procedures, and provide effective patient care.

Correct Answer: D

Rationale: The correct answer is D) Venturi mask for clients with COPD. A Venturi mask delivers precise oxygen concentration by mixing oxygen with room air through a series of valves. This is crucial for COPD clients who have a delicate balance of oxygen and carbon dioxide in their blood. The Venturi mask allows for titration of oxygen levels, preventing oxygen toxicity or worsening of respiratory acidosis. Options A and B (Cannula and Simple Face mask) deliver lower oxygen concentrations and are less precise, making them unsuitable for COPD clients who require controlled oxygen therapy. Option C (Non rebreather mask) delivers high oxygen concentrations, which can lead to oxygen toxicity in COPD clients and disrupt their respiratory drive. Educationally, understanding the rationale behind choosing the appropriate oxygen delivery method is crucial for nursing practice. It ensures optimal patient outcomes by providing the right amount of oxygen while avoiding potential complications. Nurses must be knowledgeable about different oxygen delivery systems to deliver safe and effective care to clients with respiratory conditions like COPD.

Correct Answer: D

Rationale: In cases of Parkinson's Disease, patients often take levodopa to help manage their symptoms. Levodopa can interact with certain vitamins, affecting their absorption and efficacy. The correct answer is D) Vitamin B6. Levodopa can increase the levels of Vitamin B6 in the body, potentially leading to adverse effects. Vitamin B6 is not recommended to be taken in conjunction with levodopa because increased levels of Vitamin B6 can reduce the effectiveness of levodopa in managing Parkinson's symptoms. This interaction can potentially worsen the condition and hinder the treatment process. Options A, B, and C (Vitamin B1, B2, B3) are not affected by levodopa in the same way as Vitamin B6. These vitamins do not have the same interference with levodopa's function in the body and can typically be taken without the same concerns about reduced efficacy of the medication. Educationally, understanding drug interactions, such as the one between levodopa and Vitamin B6, is crucial for healthcare professionals and patients alike. It highlights the importance of considering all aspects of a patient's treatment regimen to ensure optimal outcomes and avoid potential complications. Healthcare providers need to be aware of these interactions to make informed decisions and provide safe and effective care to patients with Parkinson's Disease or other conditions requiring complex medication management.
