test bank foundations of nursing

Correct Answer: D

Rationale: Rationale for Correct Answer (D): Checking with the pharmacy for availability of liquid forms of medications is the best action because it reduces the risk of clogging the nasogastric tube. Liquid medications are less likely to cause blockages compared to nonliquid medications. Additionally, liquid forms are easier to administer through the tube. By using liquid medications, the nurse can ensure that the medications flow smoothly through the tube without causing any obstructions. Summary of Incorrect Choices: A: Instilling nonliquid medications without diluting can increase the risk of tube clogging. B: Irrigating the tube with water after all medications are given may not prevent clogging effectively and could introduce unnecessary moisture into the tube. C: Mixing all medications together can lead to potential drug interactions and may not address the issue of tube clogging effectively.

Correct Answer: A

Rationale: The correct answer is A: Maintaining a closed urinary drainage system. This action prevents infection by reducing exposure to external pathogens. Step 1: A closed system minimizes the risk of contamination. Step 2: It prevents entry of bacteria into the urinary tract. Step 3: Regularly emptying the drainage bag helps maintain a closed system. Step 4: This action promotes patient safety and reduces infection risk. Summary: Choice B (strict clean technique) may reduce infection risk during catheter insertion but does not prevent infections post-insertion. Choice C (replacing drainage bag once per shift) increases infection risk due to frequent disconnection. Choice D (fully inflating catheter balloon) is unrelated to infection prevention.

Correct Answer: B

Rationale: The correct answer is B: Contraction of bronchial smooth muscle. Histamine release can lead to bronchoconstriction, which narrows the airways and causes difficulty in breathing. This is a common symptom in allergic reactions like asthma. Constriction of small venules (Choice A) is not a typical consequence of histamine release. Dilation of large blood vessels (Choice C) is more associated with histamine's role in increasing vascular permeability. Decreased secretions from gastric and mucosal cells (Choice D) is not directly related to histamine's effects on smooth muscle contraction.

Correct Answer: A

Rationale: Step 1: Handwashing is crucial in preventing the spread of viral conjunctivitis, which is highly contagious. Step 2: Children often touch their eyes and then surfaces, aiding in disease transmission. Step 3: Educating parents and the child on proper hand hygiene can help contain the infection. Step 4: Antibiotics are not effective against viral infections, so compliance is not necessary. Step 5: Complications like meningitis and septicemia are extremely rare with viral conjunctivitis. Step 6: Surgery is not indicated for viral conjunctivitis, as it is a self-limiting condition.
