1公式と解法
優先順位の決定と委任
解き方
- 何もしなければ、最も早く患者に害が及ぶのは何かを考えます。
- ABC(心停止では C-A-B)を適用し、次にマズローの欲求を考えます:生理的欲求は安全の欲求より先、安全の欲求は心理的欲求より先です。
- 選択肢を比較します:急性は慢性より先、不安定は安定より先、予期しないものは予期されるものより先、全身は局所より先。そして各所見を患者のベースラインと照らします。
- 緊急でない限り、行動する前にアセスメントします。緊急の場合は、他の対応の前提となる手順を選びます。
- 委任では、5つの権利(業務、状況、人、指示、監督)を確認します。アセスメント、指導、評価は看護師(RN)が行います。
感染管理と患者の安全
解き方
- すべての患者に標準予防策から始めます:手指衛生、予想される曝露に応じた個人防護具(PPE)、安全な鋭利器材の扱い。
- 経路に応じて予防策を追加します:接触(ガウン、手袋)、飛沫(サージカルマスク)、空気(N95、陰圧室)。
- 滅菌物は滅菌のまま保ちます:疑わしければ滅菌ではありません。拭かずに交換します。
- 環境内の害を防ぎます:転倒対策、身体拘束は最後の手段、火災には RACE と PASS。
- 与薬の権利、2つの識別子、ハイリスク薬の追加の安全対策を確認し、エラーやヒヤリハットを報告します。
検査値と電解質
解き方
- 値を検査室独自の基準範囲と比べ、次に患者のベースラインと推移と比べます。
- 検体を確認します:溶血、遅れ、点滴の近くでの採血は、誤った結果の原因になります。
- 値を、典型的な徴候と、その原因となる薬剤や状態に結びつけます。
- 相互作用を探します:低カリウム血症や低マグネシウム血症はジゴキシン中毒を増強し、脱水はリチウムを上昇させます。
- 患者に対応します:アセスメントし、血中濃度が危険なら薬を保留し、パニック値は復唱して処方者に報告します。
内科外科看護:循環器と呼吸器
解き方
- 問題を言い当てます:ポンプ失調、動脈の閉塞、リズム、血栓、気道の狭窄、感染、または機器の問題。
- まず危険なサインを確認します:低酸素、低血圧、胸痛、新たな錯乱、冷たく脈の触れない手足。
- 酸素は患者に合わせます:大多数は94~98%、CO₂ 貯留のリスクがある人は88~92%。
- 各薬剤を、その検査とリスクに結びつけます:ワルファリンと INR、ヘパリンと aPTT・血小板、利尿薬とカリウム。
- 安全な最初の対応を選び、その後にエスカレーションして再評価します。
内科外科看護:神経、内分泌、腎臓
解き方
- 新たな錯乱、脱力、けいれんのあるすべての患者で血糖を確認します。
- 意識レベルを脳の異常の最も早い警告サインとして使います。瞳孔やクッシング三徴は遅れて現れます。
- 糖尿病の緊急事態では、DKA(ケトン、アシドーシス)と HHS(非常に高い浸透圧、脱水)を区別し、まず輸液を行います。
- ナトリウムと水分については、ADH が過剰(SIADH)か不足(DI)かを判断し、慢性の変化はゆっくり補正します。
- 腎臓の問題では、原因を腎前性、腎性、腎後性に分け、カリウムと水分に注意します。
内科外科看護:消化器、周術期、がん
解き方
- 何が隠れているかを考えます:体内出血、発熱のない感染、正常な SpO₂ の陰にある換気低下。
- 術後の時間経過で合併症を絞り込みます:数時間なら出血、数日なら胸部の問題、それ以降は創傷や縫合不全の問題。
- 疼痛は、アセスメントし、多角的鎮痛で治療し、再評価します。オピオイドを使うたびに鎮静をモニターします。
- がん患者では、最低値(ナディア)の時期の体調不良はすべて好中球減少性敗血症として扱い、腫瘍学的な緊急事態を把握しておきます。
- 熱傷では、II度とIII度の部分だけを数え、パークランドの時計は受傷時から始め、尿量に合わせて調整します。

3溶液
1.優先順位の決定と委任
答え: A · Day 1 after bowel surgery, new chest pain and heart rate 110/min
これが答えになる理由
New chest pain and tachycardia after surgery could be a myocardial infarction or pulmonary embolism. This patient needs immediate assessment; the others have routine needs.
A · Day 1 after bowel surgery, new chest pain and heart rate 110/min
2.優先順位の決定と委任
答え: B · Talk to the assistant privately, restate what must be reported and follow up closely
これが答えになる理由
The RN gives direct, private feedback, restates the reporting limits and increases supervision. If the problem continues, it is escalated to the manager according to policy.
B · Talk to the assistant privately, restate what must be reported and follow up closely
3.感染管理と患者の安全
答え: C · The reason, alternatives tried, type of restraint, times and regular assessments
これが答えになる理由
Restraint documentation includes the behavior that made it necessary, less restrictive measures tried, the order, the type used, the times applied and released, and ongoing checks of circulation, skin, needs and mental state.
C · The reason, alternatives tried, type of restraint, times and regular assessments
4.感染管理と患者の安全
答え: A · Wear a fit-tested respirator (N95 or FFP3) and eye protection instead of a surgical mask
これが答えになる理由
Aerosol-generating procedures can spread influenza in small particles that a surgical mask does not filter well. Staff wear a fit-tested respirator (N95 in the US, FFP3 in the UK), eye protection, gown and gloves, and the number of people in the room is kept low.
A · Wear a fit-tested respirator (N95 or FFP3) and eye protection instead of a surgical mask
5.検査値と電解質
答え: A · It binds potassium in the gut so it leaves in the stool
これが答えになる理由
Potassium binders exchange potassium in the gut for another ion, so potassium is removed from the body in the stool. They act over hours, so they are not used alone for emergencies; calcium protects the heart, and insulin with glucose shifts potassium into cells quickly.確認に用いた資料: High potassium level · MedlinePlus (NIH) (2025)
A · It binds potassium in the gut so it leaves in the stool
6.検査値と電解質
答え: C · Asymptomatic bacteriuria, usually not treated with antibiotics
これが答えになる理由
Asymptomatic bacteriuria is common in older adults and usually should not be treated, because treatment brings adverse effects and resistance without benefit. Exceptions include pregnancy and some urological procedures.確認に用いた資料: Asymptomatic Bacteriuria · StatPearls (NCBI Bookshelf) (2023)
C · Asymptomatic bacteriuria, usually not treated with antibiotics
7.臨床看護学
答え: A · Reorientation, glasses and hearing aids in use, and good sleep and hydration
これが答えになる理由
Multicomponent prevention, including orientation, sensory aids, hydration, nutrition, mobility, sleep and avoiding unnecessary moves or drugs, reduces delirium.
A · Reorientation, glasses and hearing aids in use, and good sleep and hydration
8.臨床看護学
答え: C · Cardiac tamponade
これが答えになる理由
Hypotension, raised JVP and muffled heart sounds (Beck's triad) suggest cardiac tamponade. Blood in the pericardial space compresses the heart and needs urgent drainage.
9.内科外科看護:循環器と呼吸器
答え: D · Several samples, ideally including early-morning sputum
これが答えになる理由
Usually three sputum samples, including an early-morning sample, are sent for smear microscopy, culture and molecular testing. Deep coughed sputum, not saliva, is needed. Samples are collected before treatment where possible and in a way that limits exposure to others.
D · Several samples, ideally including early-morning sputum
10.内科外科看護:循環器と呼吸器
答え: B · Via a mask or humidified device over the neck stoma
これが答えになる理由
A total laryngectomy separates the trachea from the upper airway, so the patient breathes only through the neck stoma. Oxygen and any rescue breaths must be given via the stoma. These patients are "neck breathers" and often carry an alert card.
B · Via a mask or humidified device over the neck stoma
11.内科外科看護:神経、内分泌、腎臓
答え: A · Loss of movement and pain sense, with position sense kept
これが答えになる理由
Anterior cord syndrome usually follows damage to the anterior spinal artery. Motor, pain and temperature pathways are lost below the injury, but the dorsal columns (fine touch, vibration and proprioception) at the back are spared.
A · Loss of movement and pain sense, with position sense kept
12.内科外科看護:神経、内分泌、腎臓
答え: B · "I will use a salt substitute instead of ordinary salt."
これが答えになる理由
Salt substitutes often contain potassium chloride, which can cause dangerous hyperkalaemia in CKD. Patients should reduce salt without using these products. Boiling vegetables and limiting high-potassium foods are correct.
B · "I will use a salt substitute instead of ordinary salt."
13.内科外科看護:消化器、周術期、がん
答え: A · 小腸:早期の嘔吐で膨満は軽い。大腸:遅れて嘔吐し、著明な膨満
これが答えになる理由
近位小腸閉塞では、嘔吐が早期に目立ち、膨満は軽度です。大腸閉塞では、膨満が著明で、便秘が早期にあり、嘔吐は遅れて起こります(糞便性のこともあります)。画像検査で閉塞部位と原因を確認します。
A · 小腸:早期の嘔吐で膨満は軽い。大腸:遅れて嘔吐し、著明な膨満
14.内科外科看護:消化器、周術期、がん
答え: C · A bulk-forming laxative used on its own
これが答えになる理由
Bulk-forming laxatives need good fluid intake and mobility and can worsen constipation or cause obstruction without them. They do not counter the effect of opioids on gut movement, so stimulant or osmotic laxatives are preferred.
C · A bulk-forming laxative used on its own
