Correct Answer: D

Rationale: Colace is a stool softener that acts by pulling more water into the bowel lumen, making the stool soft and easier to evacuate. In the given scenario of constipation in an immobilized client, a stool softener like Colace is the appropriate choice to help facilitate bowel movements. Advil and Anasaid are nonsteroidal anti-inflammatory drugs (NSAIDs) used for pain relief, not for constipation. Clinocil is not a recognized medication for constipation relief.

Correct Answer: C

Rationale: When assessing a client's risk for elimination impairment, family history is the least relevant factor to consider. Current medications can affect elimination functions through side effects, ambulation abilities can impact mobility to access toileting facilities, and hydration status directly influences urinary output and bowel function. Family history, although providing some context, does not have a direct impact on the client's current risk of elimination impairment.

Correct Answer: A

Rationale: Tobacco use is a well-established predisposing factor for cancer of the tongue. Smoking or chewing tobacco can lead to the development of oral cancers, including those affecting the tongue. Obesity, sun exposure, and eating sweets are not directly linked to an increased risk of tongue cancer. Obesity may be associated with other types of cancer, sun exposure can lead to skin cancer, and eating sweets is not a known risk factor for tongue cancer. Therefore, the correct answer is tobacco use, as it has a strong association with the development of tongue cancer, making it a significant predisposing factor.

Correct Answer: D

Rationale: Breast implants can interfere with mammography by potentially preventing the detection of masses. The presence of implants can obscure a clear view of breast tissue, making it difficult to identify abnormalities such as masses that may indicate breast cancer. Choices A, B, and C are incorrect because discomfort, contraindications, and dislodgment are not primary reasons why breast implants interfere with mammography. The main concern is the impedance of detecting abnormalities accurately due to the implants.

Correct Answer: D

Rationale: The nurse should monitor the client's heart rate and pulse oximetry during suctioning to assess the client's tolerance of the procedure. Oxygen desaturation to below 90% indicates hypoxemia. If hypoxia occurs during suctioning, the nurse must terminate the procedure and oxygenate the client with 100% oxygen to address the hypoxemia promptly and ensure the client's safety. Rechecking the pulse oximetry reading is important, but the priority is to address the hypoxemia by providing oxygen. Contacting the healthcare provider or respiratory therapist is not necessary at this time as the nurse can manage the hypoxemia with oxygenation. Oxygenating the client with 100% oxygen is the immediate action required in this situation.
