A nurse is caring for a client who is receiving positive end-expiratory pressure (PEEP) via mechanical ventilation. The nurse should monitor the client for which of the following adverse effects of PEEP?
Hypoxemia
Tension pneumothorax.
Malignant hypertension
Atelectasis
The Correct Answer is B
A. Hypoxemia is a condition of low oxygen levels in the blood. PEEP can actually improve oxygenation by preventing alveolar collapse and increasing functional residual capacity.
B. Tension pneumothorax is a life-threatening condition of air accumulation in the pleural space that causes increased intrathoracic pressure and compresses the lungs, heart, and great vessels. PEEP can increase the risk of tension pneumothorax by creating excessive positive pressure in the airways and alveoli.
C. Malignant hypertension is a severe form of high blood pressure that can cause organ damage and stroke. PEEP can cause a transient increase in blood pressure due to increased intrathoracic pressure, but it does not cause malignant hypertension.
D. Atelectasis is a condition of partial or complete lung collapse due to alveolar collapse or obstruction. PEEP can prevent or treat atelectasis by maintaining positive pressure in the airways and alveoli.

Correct Answer is A
Explanation
Choice A reason:
"Use a cane when walking to maintain your balance" is the correct statement Multiple sclerosis (MS) is a chronic autoimmune condition that affects the central nervous system, leading to various neurological symptoms. Mobility and balance issues are common among individuals with MS, and using a cane can be helpful in providing stability and support while walking. It can also reduce the risk of falls and improve the client's overall safety and confidence when ambulating.
Choice B reason:
"Plan to take a hot bath once a week to reduce stress” is not appropriate statement. Heat sensitivity is a common symptom in individuals with MS, and exposure to heat, such as hot baths or saunas, can exacerbate MS symptoms. It is generally advisable for individuals with MS to avoid excessive heat exposure as it can worsen fatigue and other neurological symptoms.
Choice C reason:
"Engage in a rigorous exercise program to maintain muscle tone" is not appropriate. While exercise is beneficial for individuals with MS, particularly in maintaining muscle strength and flexibility, it is essential to avoid a rigorous or overly strenuous exercise program. High-intensity exercise may lead to increased fatigue and exacerbation of MS symptoms. A personalized exercise plan that considers the individual's specific abilities and limitations is recommended.
Choice D reason
"Place a scatter rug in your bathroom to prevent falling" is not appropriate statement. Placing a scatter rug in the bathroom is not advisable, especially for individuals with mobility and balance issues like those with MS. Scatter rugs can create tripping hazards and increase the risk of falls. It is essential to keep the bathroom floor clear and use non-slip mats to improve safety.
Correct Answer is D
Explanation
Choice A reason
"I can use natural-skin condoms to prevent sexually transmitted infections." This statement is incorrect. Natural-skin or lambskin condoms are not recommended for preventing sexually transmitted infections (STIs). They may provide some protection against pregnancy but do not effectively protect against STIs. Clients should use latex or polyurethane condoms to reduce the risk of STIs.
Choice B reason
"I can use petroleum jelly as a lubricant with the condom." This statement is also incorrect. Petroleum jelly (Vaseline) and other oil-based lubricants can damage latex condoms, leading to a higher risk of breakage or failure. Clients should use water-based or silicone-based lubricants with latex or polyurethane condoms.
Choice C reason:
"I can re-use the condom one time after initial use." This statement is incorrect. Condoms are designed for single-use only. Reusing a condom increases the risk of breakage, failure, and the transmission of STIs or unwanted pregnancy. Clients should always use a new condom for each sexual act.
Choice D reason:
"I can store the condoms in the drawer of my nightstand." This statement is correct because it indicates that the client understands the proper storage of condoms. Storing condoms in a cool, dry place, such as a drawer or a condom case, helps protect them from damage or deterioration, ensuring they remain effective when needed.
