Correct Answer: A

Rationale: In collecting a sputum specimen, the nurse should instruct Roy to breathe slowly, cough, and then expectorate into the specimen container. This ensures that the sputum sample is collected from the lower respiratory tract where it is most likely to contain pathogens or other relevant substances for analysis. By instructing Roy to breathe slowly, it helps him to take deep breaths and effectively cough to produce a good sputum sample. Additionally, asking him to expectorate directly into the specimen container helps prevent contamination from saliva or other sources, ensuring the accuracy of the specimen collected for testing.

Correct Answer: A

Rationale: Signs such as using tissues to doorknobs suggest that the patient is unconsciously controlling unacceptable impulses or feelings. This behavior falls under the category of defense mechanisms, specifically displacement, where the individual redirects their emotions from a threatening target to a safer one. In this case, the patient may be experiencing anxiety or fear related to contamination or germs, leading them to use tissues to avoid touching doorknobs directly. It is a way for the patient to manage their underlying emotions, albeit unconsciously, through this compulsive behavior.

Correct Answer: A

Rationale: Acute pyelonephritis is the most likely condition based on the patient presentation and urinalysis findings described. Acute pyelonephritis is an infection of the renal parenchyma and pelvis, typically caused by ascending bacteria from the lower urinary tract. The classic symptoms include fever, chills, flank pain, and costovertebral angle tenderness (tenderness over the kidneys). The presence of pyuria (pus in the urine) and bacteriuria (bacteria in the urine) on urinalysis further supports the diagnosis of acute pyelonephritis. It is crucial to diagnose and treat acute pyelonephritis promptly to prevent complications and recurrent infections.

Correct Answer: A

Rationale: Physiologic jaundice in newborns is a common and typically benign condition caused by the immaturity of the newborn's liver. The correct statement about physiologic jaundice is that it occurs due to an imbalance between the production and elimination of bilirubin. In contrast, Option A is the false statement because it incorrectly states that physiologic jaundice is caused by impairment in the removal of bilirubin deficiency in the production of glucuronide transferase. This statement is inaccurate as physiologic jaundice results from the immature liver's reduced ability to conjugate bilirubin.

Correct Answer: A

Rationale: The symptoms described - sudden-onset severe headache, nausea, vomiting, photophobia, neck stiffness, and positive Kernig and Brudzinski signs - are classic manifestations of meningitis. Meningitis is an inflammation of the meninges, the protective membranes covering the brain and spinal cord, often caused by infection. The sudden onset of these symptoms and signs, along with neck stiffness and positive Kernig and Brudzinski signs (indicative of meningeal irritation), strongly suggest meningitis as the most likely diagnosis in this scenario.
