🔹 A PaCO2 of 39 mmHg is within the normal adult range of about 35 to 45 mmHg.

🔹 This indicates the client is eliminating carbon dioxide adequately and that the ventilation provided with the bag-valve mask is effective.

🔹 When ventilation is appropriate, the nurse expects the client to maintain a normal carbon dioxide level rather than showing evidence of retention or excessive removal.

🔹 A normal PaCO2 means the nurse is neither under-ventilating nor over-ventilating the client at this time.

🔹 This finding supports that the current respiratory support is adequate and effective.

The new nurse should prepare to assist with intubation.

🔹 Intubation may be needed if ventilation is ineffective, airway protection is poor, or the client is deteriorating.

🔹 A PaCO2 of 39 mmHg does not indicate failed ventilation, so this is not supported by the data provided.

The new nurse should prepare to call a code on the client.

🔹 A code is called when a client has cardiopulmonary arrest or is in an immediately life-threatening condition.

🔹 A normal PaCO2 does not suggest respiratory arrest or sudden collapse.

The new nurse is hyperventilating the client.

🔹 Hyperventilation would usually lower the PaCO2 below 35 mmHg because too much carbon dioxide is being blown off.

🔹 Since the PaCO2 is 39 mmHg, there is no evidence of hyperventilation.

🔷 A stage II pressure injury involves partial-thickness skin loss with an exposed dermis and a pink or red wound bed.

🔷 If the wound progresses to full-thickness tissue loss with exposed subcutaneous tissue, it has advanced to a stage III pressure injury.

🔷 This represents deeper tissue destruction and confirms that the pressure injury is worsening rather than healing.

🔷 Stage III injuries extend beyond the dermis into the subcutaneous layer, which is much more serious than a stage II wound.

🔷 The exposure of subcutaneous tissue is the clearest sign in this question that the wound has deteriorated.

No presence of slough, eschar, or granulation tissue.

🔷 The absence of slough or eschar does not by itself indicate worsening and may actually be seen in a cleaner wound bed.

🔷 This finding is not the strongest sign of progression to a deeper stage of injury.

A localized area of skin with nonblanchable erythema.

🔷 Nonblanchable erythema describes a stage I pressure injury, which is more superficial than stage II.

🔷 This would not indicate worsening from stage II to a more severe stage.

Partial-thickness loss of skin with exposed dermis.

🔷 This is the definition of a stage II pressure injury.

🔷 It describes the current stage, not a worsening of the wound.

Remove the safety reminder device as soon as it is no longer needed.

💎 A safety reminder device should be used only for the shortest time necessary to maintain safety.

💎 Prolonged use increases the risk of skin breakdown, discomfort, impaired mobility, and circulation problems.

💎 The nurse should continually reassess whether the device is still required for protection.

💎 Once the client can remain safe without it, removal is appropriate and helps preserve the client’s mobility and dignity.

💎 This action reflects proper nursing judgment and reduces unnecessary complications.

Replace the device when it becomes soiled or wet.

💎 A soiled or wet safety reminder device can irritate the skin and promote skin maceration or breakdown.

💎 Moisture trapped against the skin increases the risk for pressure injury and infection.

💎 Replacing the device helps maintain skin integrity and improves client comfort.

💎 Clean equipment is also important for reducing microbial growth and maintaining hygiene.

💎 Keeping the device dry and clean is a basic but essential part of safe care.

Inspect the skin under the device frequently and with position changes.

💎 The skin under the device is at risk for pressure, friction, redness, and breakdown.

💎 Frequent inspection allows the nurse to identify early signs of injury before significant damage occurs.

💎 Checking the skin during position changes supports ongoing assessment and prompt intervention.

💎 This is especially important for clients with fragile skin, poor nutrition, or limited mobility.

💎 Early detection of skin changes helps prevent complications associated with device use.

Assess the circulation of the extremity distal to the safety reminder device.

💎 Any device placed around an extremity can impair distal circulation if it becomes too tight or shifts position.

💎 The nurse should monitor for signs such as coolness, pallor, cyanosis, swelling, numbness, or weak pulses.

💎 Circulatory compromise can lead to tissue damage if not recognized quickly.

💎 Distal assessment helps ensure the device is secure without restricting blood flow.

💎 This is a priority safety measure whenever any supportive or restrictive device is applied.

Remove the safety reminder devices every 4 hours for 10 minutes.

💎 This is not the standard safety action for a safety reminder device and is not the key recommendation here.

💎 The nurse should focus on ongoing assessment, skin checks, circulation checks, and removal when no longer needed.

✅ Effective hand hygiene requires scrubbing with soap for at least 20 seconds to remove microorganisms and debris.

✅ This duration helps clean the palms, backs of hands, fingers, thumbs, and under the nails more thoroughly.

✅ Proper hand washing is one of the most important ways to prevent wound contamination and infection during dressing changes.

✅ Short or incomplete washing leaves organisms on the hands and increases infection risk.

✅ Teaching the client to wash for at least 20 seconds supports safe wound care at home.

Dry hands with a previously used towel.

✅ A previously used towel may contain microorganisms and can re-contaminate clean hands.

✅ Hands should be dried with a clean towel, disposable towel, or air dryer.

Start washing at the wrists, moving toward the fingers.

✅ Hand washing should focus on all surfaces, but movement is generally from the cleanest areas to the less clean areas, not this phrasing.

✅ This statement does not describe the best standard teaching point for routine hand hygiene.

Lather only the palms of your hands.

✅ Washing only the palms is incomplete and misses important areas such as the backs of the hands, fingers, thumbs, and nails.

✅ Effective hand washing requires cleaning all hand surfaces, not just the palms.

🎯 The greatest immediate concern with a safety restraint device is impaired circulation to the restrained extremity.

🎯 If circulation is reduced, the client can develop ischemia, nerve damage, tissue injury, or loss of function.

🎯 Signs of decreased circulation include cool skin, pallor, cyanosis, numbness, tingling, and weak pulses.

🎯 This complication is more urgent than psychosocial or long-term concerns because it can quickly lead to physical harm.

🎯 For that reason, monitoring circulation is a top priority in restrained clients.

Contracture development.

🎯 Contractures can occur with prolonged immobility, but they are usually a longer-term complication.

🎯 They are not the most immediate concern compared with impaired blood flow.

Increased agitation.

🎯 Agitation is important because restraints can worsen distress or confusion.

🎯 Even so, circulatory compromise poses a more immediate threat to tissue viability and safety.

Loss of independence.

🎯 Loss of independence is a psychosocial concern associated with restraint use.

🎯 It is important, but it is not as urgent as the risk of decreased circulation.

📌 Before irrigation begins, the nurse should first position the client properly so the solution flows by gravity across the wound and into the collection basin.

📌 Correct positioning promotes effective cleansing while reducing contamination of surrounding tissue.

📌 It also helps prevent irrigation fluid from pooling in the wound or leaking onto clean areas.

📌 Preparing the client’s position first creates the safest and most efficient setup for the procedure.

📌 Since positioning establishes proper drainage and access, it is the first action the nurse should take.

Clean the surrounding skin with antibiotic wipes.

📌 The surrounding skin may be cleansed as part of wound care, but this is not the first priority before establishing proper positioning.

📌 In addition, routine wound care does not typically require antibiotic wipes as the initial step.

Irrigate until the solution draining into the basin is clear.

📌 This describes how irrigation may continue during the procedure, but it is not the first action.

📌 The nurse must first set up the client and the wound to allow proper flow.

Advise the client that the irrigation solution can be cold.

📌 Irrigation solution should usually be at a comfortable or prescribed temperature because cold fluid may cause discomfort.

📌 Teaching may be needed, but it does not come before positioning for safe fluid drainage.

🔵 In adults, the diastolic blood pressure is documented at the point where the Korotkoff sounds disappear, also called phase V.

🔵 This represents the pressure in the arteries when the heart is resting between contractions.

🔵 The first sound heard corresponds to the systolic pressure, not the diastolic pressure.

🔵 Accurate identification of the point where sounds disappear is essential for correct blood pressure documentation.

🔵 Therefore, the nurse should record the manometer reading at sound disappearance as the diastolic pressure.

The number in the manometer plus 6 when the sound disappeared.

🔵 Blood pressure is not documented by adding 6 to the reading.

🔵 The exact manometer value at the correct point should be recorded.

The number in the manometer when the first sound was heard.

🔵 The first sound heard marks the systolic blood pressure.

🔵 This does not represent the diastolic pressure.

The number in the manometer plus 6 when the first sound was heard.

🔵 This is incorrect because the first sound corresponds to systolic, not diastolic pressure.

🔵 Adding 6 has no role in standard blood pressure measurement.

🛑 When the sterile field becomes contaminated during central venous catheter insertion, the priority is to stop or pause the procedure immediately.

🛑 Continuing with a contaminated field places the client at serious risk for infection, including bloodstream infection.

🛑 Pausing the procedure prevents further use of contaminated supplies and protects sterile technique.

🛑 Once the procedure is paused, the nurse and provider can replace contaminated equipment and re-establish sterility.

🛑 The most urgent action for client safety is to halt the procedure first.

Document the contamination.

🛑 Documentation is important, but it does not address the immediate safety risk.

🛑 The contaminated procedure must be interrupted before any charting occurs.

Request additional assistance.

🛑 Extra help may be useful, but it is not the first priority once contamination is identified.

🛑 The immediate action is to stop the procedure to prevent client harm.

Retrieve a new sterile kit.

🛑 A new sterile kit will likely be needed, but not before the procedure is first paused.

🛑 The nurse must immediately stop the contaminated process before gathering replacement supplies.

🟣 A client with a recent stroke and left-sided weakness has impaired strength, balance, and mobility, which places the client at high risk for injury during transfer.

🟣 Stroke can also affect coordination, spatial awareness, and the ability to bear weight safely.

🟣 Weakness on one side increases the likelihood of falling or collapsing during movement from bed to chair or stretcher.

🟣 This client may require substantial assistance, transfer equipment, or a two-person assist for safety.

🟣 Among the options, this client has the most obvious physical impairment that increases transfer-related injury risk.

A client with mild dementia who follows simple commands.

🟣 Mild dementia may increase the need for cueing, but the ability to follow simple commands supports safer participation in transfer.

🟣 This client is not at greater risk than one with recent unilateral weakness from stroke.

A client with pneumonia using oxygen via nasal cannula.

🟣 This client may have fatigue or shortness of breath, but oxygen by nasal cannula alone does not indicate the highest transfer risk.

🟣 The physical motor deficit seen after stroke presents a greater danger during transfer.

A client with mild depression and low motivation.

🟣 Low motivation can affect participation, but it does not necessarily create the same immediate physical fall risk as hemiparesis.

🟣 The client with a recent stroke has the more significant safety concern during transfer.

⭐ Abduction is the movement of a body part away from the midline of the body.

⭐ An example is lifting the arm out to the side away from the trunk.

⭐ This term is a basic concept in range-of-motion assessment and body mechanics.

⭐ Correct identification of movement patterns helps the nurse document musculoskeletal function accurately.

⭐ Since the question asks for movement away from the midline, abduction is the correct term.

Extension.

⭐ Extension is the straightening of a joint or increasing the angle between body parts.

⭐ It does not specifically mean movement away from the midline.

Adduction.

⭐ Adduction means movement toward the midline of the body.

⭐ This is the opposite of the movement described in the question.

Flexion.

⭐ Flexion decreases the angle of a joint, such as bending the elbow.

⭐ It does not refer to movement away from the midline.
