The physician inserted a chest tube drainage to Mr. Alda in order to help re-expand the lungs. Which of the following should you prepare FIRST as a nurse in case of emergency when the tube is accidentally disconnected?

Correct Answer: A

Rationale: Correct Answer: A - sterile clamps Rationale: 1. **Immediate action**: Sterile clamps are essential to clamp the chest tube to prevent air from entering the pleural space. 2. **Prevent lung collapse**: Clamping the tube will prevent lung collapse and maintain positive pressure in the pleural space. 3. **Buy time**: By clamping the tube, you buy time to properly reattach the tube or secure it with a new connection. 4. **Safety**: Sterile clamps are a quick and effective solution to prevent a potentially life-threatening situation. Summary of other choices: B: Sterile dressing - Not the first priority as the immediate concern is preventing air from entering the pleural space. C: Another chest tube - Not necessary initially as clamping can buy time to reattach the disconnected tube. D: A bottle of sterile water - Not needed for emergency management of a disconnected chest tube.

Correct Answer: C

Rationale: The correct answer is C: Anaphylaxis. Anaphylaxis is the MOST severe form of an allergic reaction, including latex allergy. It is a systemic, potentially life-threatening reaction that can involve multiple organ systems. Symptoms can include difficulty breathing, swelling of the throat, a rapid drop in blood pressure, and cardiovascular collapse. Pruritus, erythema, and swelling (choice A) are common symptoms of allergic reactions but not specific to anaphylaxis. Asthma (choice B) can be a manifestation of latex allergy but is not the most severe form. Blisters and other skin lesions (choice D) are not typical of anaphylaxis but can occur in some cases of contact dermatitis from latex exposure.

Correct Answer: A

Rationale: The correct answer is A: Active artificial immunity. This is because the person's immune system is actively stimulated by the vaccine to produce antibodies against Covid-19. It is considered artificial because it is acquired through vaccination rather than natural exposure to the disease. B: Active natural immunity is incorrect because it refers to immunity acquired through natural exposure to the disease. C: Passive natural immunity is incorrect because it refers to temporary immunity passed from mother to baby through breast milk or placenta. D: Passive artificial immunity is incorrect because it refers to receiving pre-formed antibodies, such as through an injection of antibodies rather than the body producing them itself.

Correct Answer: D

Rationale: The correct answer is D: Tilt the head slightly forward and angle the bottle toward the side of the nostril. This method allows for proper administration of the spray into the nasal passage, ensuring effective delivery of the medication. Tilted head helps direct the spray towards the nasal cavity without causing discomfort or leakage. It also helps prevent the medication from dripping down the back of the throat. Choices A, B, and C are incorrect: A: Finishing instillation in one nostril before moving to the other can lead to uneven distribution of medication and reduced effectiveness. B: Inhaling quickly may cause irritation and discomfort to the mucous membranes due to the forceful intake of the spray. C: Blowing the nose after spraying can expel the medication before it has a chance to be absorbed, decreasing its efficacy.

Correct Answer: C

Rationale: The correct answer is C: Nasal polyps. Nasal polyps are benign growths that form in the nasal cavity and sinuses, leading to symptoms such as chronic nasal congestion, hyposmia, and anosmia. The presence of polypoid masses seen on nasal endoscopy is characteristic of nasal polyps. Rationale: 1. Chronic nasal congestion, hyposmia, and anosmia are common symptoms of nasal polyps. 2. Nasal endoscopy revealing polypoid masses confirms the presence of nasal polyps. 3. Allergic rhinitis may cause nasal congestion but does not typically present with polypoid masses. 4. Chronic sinusitis can cause nasal congestion but is usually associated with inflammation of the sinuses, not just polypoid masses. 5. A deviated nasal septum can lead to nasal congestion but does not typically cause polypoid masses obstructing the nasal cavity and sinuses.

Correct Answer: A

Rationale: Correct Answer: A - Genetics Rationale: 1. Genetics refer to an individual's inherited traits which can influence health conditions and predispositions. 2. Genetic factors can impact an individual's susceptibility to certain diseases and conditions. 3. Health beliefs and practices may be influenced by knowledge of one's genetic predispositions. 4. Family structure, socioeconomic status, and living situation are external variables that may influence health but are not inherent to the individual like genetics.

Correct Answer: C

Rationale: The correct answer is C: Systematic sampling. Nurse Sandy is adopting systematic sampling by selecting every third patient with MI after a random start. This method ensures equal chance of selection for each patient and maintains randomness. In contrast, simple random sampling (A) entails each patient having an equal chance of being selected independently. Stratified sampling (B) divides patients into groups based on certain characteristics, which is not the case here. Cluster sampling (D) involves grouping patients and selecting entire groups, which is different from the individual selection in this scenario.

Correct Answer: C

Rationale: The correct action in this scenario is to choose option C: put a line across the sentence, make the correction over it, and sign. This method is recommended because it maintains the integrity of the original record by showing what was initially written and clearly indicating the correction. By crossing out the error, making the correction, and signing the entry, the nurse acknowledges and takes responsibility for the mistake while ensuring the accuracy and transparency of the documentation. Option A is incorrect as crossing the error many times can make the note illegible and may not clearly indicate the correction. Option B is incorrect because using correction fluid can make the note messy and may raise suspicions of tampering with the record. Option D is incorrect as erasing with a rubber eraser can damage the document and also raise concerns about the validity of the information. In summary, option C is the best choice as it allows for a clear and professional correction without compromising the integrity of the progress notes.

Correct Answer: D

Rationale: The correct answer is D because a journal article about a study using large, previously unpublished databases is a primary source as it presents original research findings firsthand. It contributes new knowledge to the field. A textbook (A) compiles existing information, not original research. A doctoral dissertation (B) critiques research but is not a primary source. A published commentary (C) interprets others' findings, making it a secondary source.
